NO is usually timing related.

HC and CO are combustion efficiency related. Anything from a bad O2 sensor, coolant temp, vacuum leak, spark plugs, wires, cap/rotor can affect it.

If all those items are fairly new and it still fails by a lot, it could mean new cat time.

Well I just finished putting a new cap and rotor on and I had already done the spark plugs and wires so hopefully it will pass now.

Took the civic over to the local emission place today. Failed HC ppm, CO and NO ppm. Any suggestions?

Nah, just a self-centered drunkpost about my own car which doesn't help you. Basically, your suspension post inspired me to do my lower ball joints which were mangled to gently caress and on the right side missing the boot completely. Unfortunately I forgot to un-bend the caliper backing plate I bent a little in the process, so on its inaugural 500ft test drive I heard the noise, pulled it pack into the garage and decided to drive a different car until I was less sore and felt like climbing under the fucker again.

You failed all 3, good job! :haw:

NO is usually caused by high combustion chamber temps. How far advanced was the timing, and were you able to get it to 14-16 degrees within the distributor's field of movement? If not, your timing belt might be off by 1 tooth (though on the D series SOHCs, they usually won't even start with it 1 tooth off).

HC and CO just means it's running rich as gently caress; usually a bad O2 sensor or an engine that's not warming up fully; anything preventing it from entering closed loop operation. I'd chuck a new O2 sensor at it personally; use Denso or NTK, get the one with the connector. Denso is the OEM, NTK is a division of NGK (who is the OEM for your spark plugs). Also, which plugs did you put in? NGK Copper or NGK Platinum will work best, and the NGK Coppers are dirt cheap.

Also, you did jump the service connector prior to setting the timing, correct? It's the same connector you short to get the check engine light to flash out codes. If you didn't, you'll need to do it again. Most manuals don't mention this, and the FSM is very vague.

Start at 16 degrees, see if they'll do a "test smog" for you (no or lesser charge). If NO is still high, back it off to 15... still high? Try 14. HC and CO will probably go up in relation, but NO should go down. You have to find the perfect balance.

There's also the option of tossing a can of Dry Gas in when you're sitting at a half tank or so. Doesn't work so well in areas with high ethanol content in their gas, but it may help a it.

Finally, you HAVE burned through all the old, stale gas that was in the tank, right? Right? Because that will put out some horrific emissions numbers.

I think the timing was advance by a good 8-10 degrees. It was way off. I did remember to jumper the service connector and now its dead center on the red mark. When I changed the plugs I got the NGK coppers and I believe the new O2 sensor is a Denso I'll have to check again when I get home. I have not burned through all the gas yet but its getting low now so I'll probably fill it up a little today.

Goddamn, I didn't think there was even enough movement allowed for 10 degrees. Guess I was off.

NGK Coppers are what they shipped with from the factory on prior years; I'm not sure what year they made the transition to NGK Platinum (pretty sure it was mid 90s on most Hondas). The only difference you'll notice is you'll have to change them every 20-30k instead of 100k and about a $1-2 difference per plug.

As long as you didn't use a Bosch O2 sensor, and you used one with a plug instead of a generic, you should be good to go - 80s/90s Hondas seem to really hate Bosch O2 sensors for some reason.

If there was a red mark, that was someone marking the distributor with a marker prior to removing it. There's no markings from the factory on the distributor or head for timing; they count on the keyed shaft and limited range of movement to keep you from going too crazy.

Honestly, I'm betting the old fuel was also playing a decent factor. But yeah, timing being off will make it fart out all kinds of nasty poo poo.

The red mark I'm referring to is the factory center timing mark(16 degrees) on the crankshaft pulley. I set the timing back to that and the exhaust ran much cleaner and didnt really have a smell to it anymore where before it was rich and gassy.

I'm not really sure what the numbers were on the second test as I can't find the paper anymore but they were significantly lower than the highest numbers allowed.

Edit: You guys think theres anything worth salvaging off the old engine?

Let me just say how much I loving HATE doing spark-plugs on those. Otherwise reliable; my boss has had one for ~a long time~ now and I've only had to work on a few things for him, and he had some clutch issues last year at around 160k mi. The clutch issues are more due to his driving than anything else, I have never seen someone ride the clutch so badly.

It is a nice one. Super clean inside just needs a new lid on the arm rest storage place. Do you guys know what the jack locations are? I'm trying to lift the front end to take off tires and replace the shocks.

I've always jacked up my '98 Ranger (same as I do on my GMC) from the center of the front crossmember and the center of the pumpkin on the rear. A '94 will be different but probably not so much that it wouldn't work there too.

You can also generally place the jack under the lower control arm around where the spring mounts to it (for the front). For the rear, you can usually jack under the spring mounts.

Assuming you're only wanting to lift one wheel at a time anyway. If you want to lift both, then follow IoC's advice, except add wheel chocks (especially if you're lifting the rear, since the moment a single rear wheel is off the ground, the truck is essentially in neutral, depending how the diff is setup). Chocks are a good idea in general, you don't want it going to visit the neighbors :v: (or rolling off of jack stands/jacks).

I ended up doing one wheel at a time with the jack under the lower control arm. Thankfully the rear shocks didn't require lifting anything to change.

Now on to the next issue with it. Idiot at the oil change place the PO to it to didn't bother draining the old oil just added a bunch on top so it was really badly overfilled. I drained the oil and replaced the filter and put in some synthetic but now I noticed when the engine is running in park I can hear knocking and when I change into any gear it gets quieter but its still there. Some people on the explorer forums said it could be a dirty MAF sensor, intake needs some cleaning of carbon buildup or some of the lower intake bolts need retorquing. I figure I'll try and tackle that today after I get new tires put on.

Over filling on engine oil is a good way to actually starve the engine for oil. When it's way over the crankshaft whips through it in the pan and aerates it to hell. Once that happens the pump can't reliably suck it up and maintain pressure.

I fear that you've got a hosed bottom end in that engine :(

Well it ran for about 40 miles before I discovered that(I didnt start the engine again till the oil was changed out). It never overheated or anything and the knock I was hearing before went away after driving a few miles. I'm hopefull it didnt have enough time to do much damage.

You should have red safety plugs. Disconnect the airbag from the harness and connect it to the red plug. For all I know the plug does nothing more than keep dust and static out but it made me feel safer. The steering wheel has a trim piece covering the airbag connection and the plug snaps into the trim for storage. You should see the passenger connection and plug behind the glove box.

For my model the Haynes manual explicitly states that the AC has to be discharged. I don't see it mentioned here so I guess you're not forced to deal with AC. But if you had planned ahead this would be a great time to clean out any coolant or other poo poo that collects in the evaporator tray. Don't forget that the heater box has one nut holding it from the engine side.
