I have a 1989 Camaro RS with a 350 TBI 5.0L and the car is running very rich and when you step on the gas it wants to die, when the car warms up the wanting to die goes away but not the running rich part.

Any Suggestions of what it could be?

 

Hey man i've got the same deal w mine, start with the basics, oil change, fuel filter, spark plugs, and if that doesn't fix it change your oxygen sonsers. Then take you throttle body of and apart and cleab the **** out of it.

 

I agree with the oil and plugs part, calm down on the tearing into it or buying o2 sensors just yet.... there isnt any sence in throwing money at it till you figure it out, run some tests first. When was the last tune up? if its been a while you might want to consider changing the oil and plugs and basic tune up stuff, next do a compression test and a vacume test at the manifolds, also check the timing and adjust it...

 

Start by checking the plugs they will tell you a lot. Clean them up before putting them back in. Also run some sea foam in your vacuum lines and in your fuel.
