Why don't you sign up for the $500 max out of pocket indianacare plan, get your hip replaced, then stop paying. The money you save will let you swap in an auto since you can't push the lightest weight clutch ever.

Alright, I've had it with this drat thing.

A few weeks ago, the car (1995) developed a timing/igntion/fuel problem. When cold, and ONLY WHEN COLD, it will fall flat on it's face while accelerating. The exhaust pops like it's retarded badly, but if it was a bad CAS it would do it all the time. Sometimes it acts like it could be a fuel starvation issue, but again, it runs fine when warm all the way from idle to redline. Sometimes it acts like it could be the coil/plugs/wires, but again, FINE WHEN WARM. Once you get over 4kRPM it catches itself and runs quite nicely.

I haven't done jack poo poo with it yet, not even pulled the plugs, because I'm at a complete loss of what it could be. One of my strengths in working on cars is diagnosing the problem, not just throwing parts at it. I'm thinking it could be a few things: the airflow meter, the ECU coolant temp sensor (my biggest suspicion: I mean, if the ECU is trying to run the car like it's warm, when it's not, wouldn't it run like poo poo? But then why does the 4k+ map work just fine... ARGH), the ignition set, or the CAS.

Can I get some input? I'm not as good with BPs as I am with M20s.

One of the coils is probably dying. My car did the exact same thing, I replaced both the coils and it eliminated the issue. Also I would clean the throttle body if you haven't done that yet.

Replaced coil, plugs, wires, ECU coolant temp sensor (EDIT: and I did shoot carb cleaner down the throat of the throttle body and got it shiny again). Car is still doing this bullshit. What's next, AFM/MAF (I don't know which one a '95 1.8 has) and/or related circuitry?

Does anyone know or have a link to NC airbag light flash codes? I've found them for NA/NB, but not for newer. I'm seeing two slow flashes, pause, then two fast flashes.

e: the internets suggest that it's either a loose connection or a $500 sensor. woo.

Back when I was keeping track of MPG in my supercharged '00 I was getting about 24 mpg combined, keeping my foot out of it. I just got 3.63 gears installed though so I'll see what happens.

Maybe I drive like a grandma but I get 30 mpg pretty consistently doing 80% highway. I'm actually kind of surprised considering I'm at 4k+ rpm constantly while on the highway.

Grandma spotted.

Also doing 80% highway is going to help your average mpg significantly.

Even though it's small and light I don't think the miata's coefficient of drag is very good (top down especially), the gearing has you at 4k on the highway and it's an old rear end engine.

I dunno, I just always expected such a light car with a tiny engine to have decent fuel efficiency. To be fair, the numbers I mentioned before were with my daily commute; not stop & go bumper-to-bumper traffic, just relatively brief average suburban commuting. When I drove the MSM home right after purchasing it I did get 30+ mpg on the highway doing like 70-90 mph or whatever. This was with me drafting behind semi trailers a good portion of the drive. :smugdog: Also, I'm pretty sure the tires were quite under-inflated, so proper inflation would've boosted that number. (The log book for my MSM is in the car, which is in storage, so I can't quote from it at the moment.)

Looking back at the fuel log from my NA, I took a moderate highway drive (120 miles) in it one time and got 30.36 mpg; the fill-ups before and after that were 23.37 and 25.13, respectively. So yeah, it seems like the type of driving is a huge factor in fuel efficiency.

With the MSM, IIRC 65 mph in 6th gear puts it at 3500 rpm, which is kinda nice because that's when the turbo kicks in, so I was able to just stomp on it and accelerate to pass in top gear.

As far as the Cd goes, the Miata is apparently 0.38, which is not that great. A Tesla S is 0.24, and plenty of recent cars (Mazda 6, Camry, etc.) are <0.30. An Escalade is apparently 0.36. :stare:

I just wonder exactly how much drag impacts the fuel efficiency on the Miata (compared to the other factors.)

Tracking my mpgs led me to discovering that I had a sticking caliper. Otherwise, I might have had more parts to replace than just the pads and the caliper.

It takes almost no effort to do a quick calculation and make sure that everything's running normally.

One of the guys on GRM actually swapped a 1.3L Festiva motor into a Miata and is getting pretty reasonable fuel economy even when he beats the poo poo out of it. He's also tried a few of the internet-kook "fuel saver" techniques in order to debunk them.

He's building his own engine dyno right now so he can test various mapping strategies without the unpredictability of a road test.

I think he takes a perverse joy in watching "enthusiasts" freak out about how he's ruined the car. Personally, I love it, dude is a genius.

There's one other nc owner in my town I've met with a silver miata, whenever I see him, he's always hypermiling. On the flipside, literally every-time I've seen that miata, it is spotless and its silver color looks absolutely amazing. It's winter mind you, and I can't even make it back from the car wash without getting a fresh salt stain in vermont. I dunno how on earth he does it.

If more power makes a Miata less of a Miata, then the inverse must be true as well. It's so simple!

In the Midwest. Granted it's hard to move a Miata here in the winter, so it's possible that I just haven't been clued in. If Clubs get down to the $22K range I'm definitely making the switch.

That guy is the poo poo. It was funny when he first posted on the Festiva forum about the thing, because about most of their members had swapped B6s and BPs into their cars and they were confounded that someone was doing basically the opposite. I imagine the reaction in the Miata community was doubly hilarious.

Yeah, Miatas (and most convertibles really) are plentiful here in FL and not all that special, so you can get the nice ones a lot cheaper than up north.

Years ago I bought my mother in law a '91 automatic for 3k and sent it up to her in NY. She recently sold it for 5k :v:

I just want to say how much I miss my '97 NA, even though it had a salvage title, 217,000 miles, and was completely rusted out to all hell and back, it was still the most visceral car I have ever owned. Even in it's delapidated state I drove it for a full year without problems and even placed 3rd overall in an autoX. The rawness, the sound, the light weight, the perfect steering, and the worlds greatest shifter are something I remember every drat day.

I have a Fiesta ST now, which is super loving awesome and way faster/more practical, just feels a lot more… sanitized. I really want to buy another Miata but I just can't justify having two cars anymore. Once my ST lease is up at the end of this year, I may just have to snag an ND. It really looks like it's going to be a "new" NA.

Either that or I'll find a clean PRHT NC, but how far away from the pureness of the NA is the NC?

It's a better NA with some torque.

Basically anyone who whines about "purity" and insists that the NA is best Miata shouldn't be listened to. All 3 generations are solid winners, each have their pluses and minuses, but they're all competent and extremely fun to drive.

They do sell belt conditioner at the auto parts store. You could give that a shot and see if it helps. I would still check the tension on them, it should only take a minute to do before you spray on the conditioner.

Your rubber is now 7+ years old and has seen lots of weather changes. I'd spend the $30-40 and change the belts now. It was a really easy job on my NB (two separate belts), not sure how bad it is on the NC.
