2002 cavalier tune/rich problem
Wednesday, April 09, 2014 9:43 AM
I have a 2002 cavalier circle track car. It is mostly a stock motor. Just had the motor rebuilt and ecu programmed. Now it runs very rough till it warms up. Then it gets better when its warm except it idles real rough. Definitly running rich. Any suggestions? Thanks

Get an AFPR to adjust the base fuel pressure.
Cheaper than a retune

Who tuned the ecu?


GMR has got nothing on this

Sounds like the tune is the issue.

I also concur that it sounds like an issue with the tune itself.
