300+ miles out of a single tank? Not bad!

I'm getting about 15mpg in my 5.0 haha

The only things I've noticed with mine is that I hear a click or thunk when decelerating right about 2k RPM.

I've also been super spoiled by my E46 BMWs with the Harman Kardon system.. these speakers sound so flat. Decent bass, decent highs (when pushed up -- can't adjust a full EQ, just bass + trebel -- electronics package sync /w nav), but everything sounds muddy. I might get the Shelby / Kicker 6x8s as they're plug & play, but the Kicker 8" subs look so nasty with the new trim ring.

My '07 has the Shaker 500 and I think it sounds awesome. I don't have lots of experience with car audio, though. My previous car ('99 forester) had the shittiest audio system on the planet.

Also, Windveil Blue is the best mustang color.

I imagine removing the top-speed limiter, like the rev-limiter, is a rather trivial operation if you want it done.

Also, my V6 came with ZR-rated tires, so I think Ford sort of expects people to end up doing this if they want to.

Yeah my 2007 v6 came with ZR pirellis, but for every one like ours there are a dozen base models with shitbucket all-seasons.

Also, the 7500rpm redline in the boss is a beautiful thing. The 5.0 must sound loving insane when revved that high.

I've got a question about my '07 4.0. I'm getting a rubbing/vibrating noise when the car is in neutral with the clutch out, but it goes away completely when the clutch is in. It's quite noticeable when sitting at a traffic light, for instance. It's like opposite of a bad throwout bearing. There's also sometimes a bit of a rattle from the shifter when accelerating in 1st and 2nd gears. I took it to the dealer and they claim that it's normal transmission noise, but with some googling I found other people with the same issue who claim there's a tsb for this.

Here, for example: http://www.mustangcollective.com/showthread.php?t=26281
and here: http://www.justanswer.com/questions/1coa0-my-wifes-2006-mustang-bought-new-has-what-sounds

Is this really a normal noise? Or do I need to be more insistent with the dealer that it's a problem? Also, would this be covered under the bumper-to-bumper warranty (which is expired) or the powertrain warranty (which is still in effect)?

Speaking of rear ends, I took my '07 in for another look at a different dealer and they decided that much of what I thought was tranny noise was really a bad bearing in the diff. So, a day and a half later and it has a freshly rebuilt rear end. It's much quieter on the highway now!

Though, it is a 7.5" so only time will tell when it explodes again. Is it worthwhile to swap a 7.5" lsd into it, or is it a better idea to just swap in a whole 8.8 axle? Some people claim the 7.5 is made of glass, while others seem to think it's reliable up to like 300hp (more than my 4.0 will ever make).

What I enjoyed about that episode was how they dyno'd that particular GT500, found that it made less than 500 hp at the rear tires (no poo poo) and then spent the rest of the time making a big deal about how it 'wasn't actually' a GT500.

The best part was when they put the '65 or '66 or whatever on the dyno and then whined about how it was "down on power" as well. Even setting aside the flywheel vs. tire horsepower difference, do they seriously not know the difference between gross and net horsepower?

I'm sure someone will defend them and say they were just being silly for the sake of tv or something, but it came across as pure, unabashed ignorance.

Edit: Also, I distinctly remember them saying that the GT500 didn't have an LSD. I find that pretty loving hard to believe, surely it had one. Every GT has had one since the mid-80's!

Make fun of the T5 all you want, but it's served us well for 30 years :colbert:

Anyway, I have a question. My '07 has developed a chirping sound when the blower is on. It varies with blower speed; it's slow on 1, annoying on 2, and fast enough that it's not really noticeable on 3 and 4. If I rev the engine it will change a bit. I changed the cabin filter and although it was dirty as poo poo, it didn't fix the issue. So it's either the blower motor or the resistor. How do I tell which one? Because it varies with engine speed (and thus alternator output) I'm tempted to think it's just the resistor, but maybe that's wishful thinking because it's cheap.

Do you have any solid numbers about the tune on your 4.0? I have an '07 v6 and I've been thinking about getting a tune, but I was unsure what kind of gains it would actually see. Did you actually gain any power or does it just remap the throttle more aggressively? I'm trying to decide if an intake, tune, exhaust, LSD, or solid driveshaft is the best thing for my otherwise-stock car. It's a pony package so I already have 235/55/17 tires and the rear sway bar.

Counterpoint: the 4.0 was a terrible motor in 2005, and in every year before that all the way back to its hideous, maligned birth somewhere in Satan's armpit.

I disagree. When it debuted in 1997, other engines available were:

302: 210hp
4.6 mod: 215hp
chevy 4.3: 180-200hp
3800 SII: 205hp
Chrysler 318: 230hp

Yes the engine was dated by the time 2010 rolled around but it's a stout engine with a good torque band. It also responds very well to FI.

Hey, he included the 302, 4.6, and Chrysler 318 to try and show how 'comparable' the 4.0 was back then. Not every engine in 1997 was an anemic turd.

I included small v8's just to give some perspective for what slightly bigger engines got you in 1997 compared to the v6s. No poo poo an LS1/LT1 is better, that's an entirely different league of engine. And the 255hp vortec really isn't that impressive considering it has a 1.7L advantage and only makes an extra 45hp.

No, you don't need royal purple gear oil. But do make sure they use the right weight. Ford calls for 75w-140 synthetic in their recent rears, which is heavier than what most rear ends use.

It feels like the stock tune or whatever is holding a ton of power back. In 2nd and 3rd it pulls hard though.

It is held back. Drive-by-wire throttle allows for all sorts of tricks like this. Many high-power cars limit torque in 1st and sometimes 2nd gear (the MS3 does this too, for example). It's so idiot drivers don't swing the rear end out and crash every time they mash the gas and pull out of a parking lot or something. Or, in the MS3, it's to reduce the torque steer from "herculean" to "bad." It probably also saves many transmissions from being blown up by these same idiot drivers.

I have the shaker 500 in my '07 and I think it sounds pretty good, but I am not an audiophile by any stretch. It sounds much better than the stipper-spec system in my old subaru and our jetta, but that's not saying much. It sounds good enough that I won't put money into it unless something breaks.

On a side note, I had to put foam tape at several places in the door panels because the door-mounted subs would make things rattle. The '10+ models should have better interior build quality so maybe it's not an issue now.

Anyone? Apparently the car has a 4.0 v6. Rock auto doesn't have any obvious tps switches or sensors that stand out on me. I'll have to troll the mustang sewers of the net to see what I can dredge up.

Yeah it's the 4.0 sohc, same engine as is found in the explorer and ranger. It's drive-by-wire in this application so I'm guessing the P2135 is referring to the sensor on the pedal itself. I believe that would be the "Accelerator Pedal Position Sensor" on rockauto under "Body-Interior." P2106 is probably a symptom of P2135. I'm not sure though--I've never seen that particular code before. I've never seen a problem with any DBW system before, actually. I would seek a second opinion before throwing a $100 part at it.

You may want to try taking the pedal assembly part, cleaning it all, and putting it back together.

Probably neither. Cars don't have perfect weight distribution. It's pretty normal.

It will be especially noticable on a car with a live axle because if one tire is up on a bump or something it also moves the other tire. My parking lot at work is a very uneven gravel lot and sometimes the gap between the rear wheels and the wheel wells are hilariously uneven.

EDIT: also, it has nothing to do with "masterful american engineering" it has to do with the fact that the car sits on springs.

From what I can tell, I need to replace the entire LCA, right? And I can get the GT500 LCAs and they are a direct-fit upgrade, right? How hard are they to change? Does anything need to be press-fit? I assume not because it's all one piece. Basically I'm trying to figure out if I can do it with hand tools and jackstands in my garage. I've had a hard time finding any pictures of the process.

Is there an actual good place for cupholders in a car with a small interior?

My old forester had a slide-out cupholder on the dashboard right below the a/c vents and it was great in the sense that it didn't interfere with the shifter, but then it had the downside that any condensation or spills fell right onto the a/c controls and the stereo headunit.

I think the center console (like s197s currently have) is probably the best spot overall but they're all a compromise.

1. What if I kept/rebuilt/modified the T5 that came with the XR4ti? IIRC, Mustang GT's were sold with a 4.6 and a T5 for about a decade or more.

To expand upon what Lord Gaga said, the T5 came behind the 302 from 83-95. The T45 was introduced along with the 4.6 in 1996, and the TR3650 came in 2001 and ran until the MT-82 in 2011. It's confusing because all of these transmission changes occurred mid-generation.

It also makes SN-95 cars annoying because the 302 is a better engine than the non-PI 4.6, but the 302 is stuck with the weaker T5.

Okay, so my 06 gt w/146k miles is running rough once it gets up to operating temp. I took it to a place to get some diagnostics run, and they said that they didn't pull any codes, but they think a tune up is probably in order. That seems reasonable, but the pricetag for that is 750 bucks.

Holy hell.

Now, I'm not a veteran auto mechanic, but I do know enough to do my own basic maintenance. Why the hell is a tune up on a 3-valve 4.6l modular so expensive? Is it due to complexity, and if so, is this something I should try to do on my own?

Also, is this bullshit, is there a different reason why I'm having problems?

Changing the spark plugs is hilariously awful on the 3-valve modular. It uses really long spark plugs that like to break off in the head, which then takes a special (expensive) tool to remove the broken plug. Most shops are going to charge a lot to do it because they know that most likely at least one plug is going to break. A shop near me charges $500 labor (plus parts) for plugs on the 3-valve. Have the spark plugs ever been changed? If not then that's a good place to start. 146k is a lot for original plugs.

You can do it yourself, changing plugs is not hard in and of itself, but make sure you are 110% prepared to deal with it if one breaks.

I would rather do a 4th gen because at least the plugs aren't going to break off in the head and leave you hosed. It's a pain in the rear end, that's for sure, but at least you can trudge your way through to success and you aren't at random luck's mercy as to whether the plugs will break.

Oh you've got lots of experience then. If it were me, I would do the plugs myself and pray they came out fine, and then have it towed to a shop just for removal of the broken ones if any of them broke. I bet that would end up being cheaper than paying a shop to do it all, even if a couple broke. But certainly get some quotes and see.

If you're curious, here is the TSB from ford for how to change the plugs. This is technically for the F150 but it's the same on the Mustang. http://www.f150forum.com/f12/must-read-before-you-try-change-your-plugs-5-4l-3-valve-engine-198/

Basically, the idea is to back the plug out 1/4 turn, douse in penetrating oil, tighten and loosen 1/4 turn a bunch of times, and hope the bottom half of the plug has come unstuck by the time you start backing the plug out all the way.

The seller claims it "needs a new compressor." I've never really messed with AC before, and I especially have no idea how the separate units like this work. I'm going on the assumption that it's totally hosed and would need to be completely rebuilt. Any ideas what that would cost?

They change the airflow properties around the MAF (by having a bigger diameter or a different number of bends or whatever) which causes the engine to run poorly, but that doesn't mean it's actually any better. Just different.
