Yeah whenever your HC's and Nox is high it usually indicates a rich running condition. As Gleep said, check the air filter, plugs, wires, cap,rotor and O2 sensor. Something is causing the engine not to properly burn all of the fuel in each cylinder.
I'll get right on that. I'm sure the thing hasn't had a tune up in years, we barely drive it anymore. So then the cat you think is still good? I guess thats good news. How come the check engine light isn't being triggered maybe its just burnt out, haha.
I'm pretty sure the air filter is good, I think I just changed it last oil job, but I'll pull the plugs and take a look. Thanks for all the help. I'll be back when I see whats up with em
Back again. Yea the air filter wasn't the cleanest, but it wasn't to too bad. I replaced it anyway. I got 3 of the sparks out, no problem. They were shot, caked with a white nastyness yeah, pretty bad. But, the rears are like impossible to get too. Is there an easy way of doing this? I'm not used to working on a V 6 like this. Why do they make a simple tune up so hard to do
Lastly, I remember hearing little tricks about passing emmisions. Something like adding a bottle of alcohol, and using the best gas, stuff like that. Will that help in my case??? and is that like rubbing alcohol you buy at the drug store or something special? I'm trying to get any thing I can to make this work.
sorry to bring up an old thread, but I'm almost there. I changed the sparks and serp belt and got a reinspection. The HC passed this time, but the NOx is still 200 to high, but at least it came down some.
I got a new EGR, but I have no idea where it goes. I looked under there for a good while and found nothin that looked like the new one. Where are they typically found???
This trick will make almost any car pass an emissions test. Change your oil then go straight to the testing station. make sure the engine is warmed up to operating temp. Brand new oil will absorb almost 100% of your emissions for about 300-500 miles. I have never had one fail the test. One jeep i owned had the catalytic converter removed and it still passed....hope this helps you

I seafoamed the crap out of it the other night, man that was so funny. The hole block was like a smoke screen on a beach invasion or something, hahaha. Anyway, I can deffinatly tell that the smell of the exhaust has changed for the better, so hopefully thats enough to pass it, but to be safe, I'll change the oil too, thanks.
