I have a 1993 Grand Prix with a 3.4L engine and my check engine light comes on. I checked the codes and get #35 and #43. The engine was rebuilt on the car 3 years ago but it has only been driven 1K miles since. I know that the idle air control sensor was replaced but the engine was not running correctly so it was not able to be set. Now I see that to set this I need to pull the ECM fuse, but there are fuses on both the drivers and passenger side and the covers that the labels are on have been painted over so I can't figure out which fuse it is.
