Idles rough after warm up
I recently purchased a 94 C4, (So I don't know the history) When you start the car it runs fine, after it warms up the check engine light comes on and it idles rough. Seems to be consistent, on time driven before it starts acting up.
Codes say lean on the right side, and spark pulse.
I think I have narrowed it down to either a Programming in the ECM or the distributor.
It looks like the previous owner may have had issues or tried to do a cheap tune.
Only other issue I have is Fuel MPG is 12.5
Any Ideas on where to go from here?
Thanks Mike
