Idle during low rpm
Hi thanks for the add. I have a 92 GMC step side with just 50k miles on it. It does have its issues probably from sitting to much. After starting it runs fine till I get to 20 mph then it gets rough till I give it gas or get off the throttle. I have changed the IAC and TPS no codes come up. Any ideas?
Thanks
Thanks
