Thats what u get driven a honda......

Timing should be a none issue, its within spec...since it passed the functional timing check, but failed for emissions..

i know the egr valve ain't cheap.
i would first do a functional test on it, to see wether its ok first, before throwing u money away.


Good luck

BTW check to see how good the cats working...many times a bad 02 will destory a cat converter...

if the car is used to feeding performance parts that ask for more fuel and you take them off the car will still give that much fuel..it won't be burned..hence rich. Not that this is his problem.

But I pulled a bunch of stuff off my car to see the state ref and I was getting 24mpg. I reset my ecu. Put about 500 miles on it and it was running around 31plus mpg. I passed with like 10% of allowable. So clean.

his problem looks more like a bum cat or needs a new 02 sensor to me. But the ecu deal worked for me.

I passed with a 270 cam in my car.

I failed smog with high NO readings a few months ago on my '87 integra, similar to you. A mechanic friend of mine recommended I change the CAT and that resolved the problem. I had the work done over at Kwik-Way in Santa Clara for like $130 for one of them high flow cats(took them 10 minutes). That should give you a reference if you need to get a new cat.

good luck.
