ok i have a 95 firebird 3.4L, whin i start the car in the morening it runs realy rich this clears up. if the car sits and idles i will get a ses light but whin i drive it it will clear up. some times the ses light will come on whin driveing and the car will fall on its face after 3000 rpm's. i dont have a cat and have tryed to scan the ecm for codes but have had no luck. if eny of yall hav some ideas it would be great.

Re: Help Pleas

Upgrade your ground wires if you haven't to a larger gauge. That fixed my rough starts in the morning.

Re: Help Pleas

Well if you don't have a cat then there is your answer. nothing is wrong. you never did a 02 sensor delete or an 02 sim??? otherwise you will have the light and a little roughness

If sounds a lot like my car. Listen for your fuel pump. Mine started doing things like that then the fuel pump went out. It will gradually run richer for longer times if that's the case.

well now that i changed my O2's it is running great, i was just wondering what that code ment. the scanner gave me the codes 76, 77, 15, 63, 13, 64, and 82. 76,77, 63, 64 all showed to be O2 15 was the egr and 13 was the AC but i dont know exactly wat 82 is or means.
