I just took my car in for emissions and failed the idle part on both the HC and CO2. I passed with flying colors on the cruise portion. Any ideas where to look? I have brand new injectors, spark plugs, cap, rotor, EGR valve, etc. Thanks guys.

Return your timing to 10 deg. BTDC.
It is possible your 02 sensors are at fault, any codes from the EEC?
Can your bring your Fuel pressure down a touch? (2 psi or so)
Is your smog pump hooked up? Are you pushing air into the cats?

I dont have an AFPR so I dont know how to bring it down. All my smog equipment is hooked up and should be functional. Why would I lower my timing when a higher timing makes a car run more lean (or am I confused)?
