Tmccurry Posted June 12, 2017 Share Posted June 12, 2017 I have what I feel is probably an easy to solve problem for a real mechanic. When I have my a/c on and I roll to a stop, the car drops ~400rpms and kind of stutters before returning to normal idle. With the a/c off, no issues. I feel like maybe I have a weak alternato or maybe my compressor is going bad? Not sure if I matters, but the car is tuned with Fp geeen and id1000cc. Stock block.

relative4 Posted June 12, 2017 Share Posted June 12, 2017 Given those mods, you should really send a log to your tuner. Link to comment Share on other sites More sharing options...
Tmccurry Posted June 13, 2017 Author Share Posted June 13, 2017 I have previously, and the fueling looked good. I guess it can't hurt to try again. Link to comment Share on other sites More sharing options...
