Does anyone know what I need to check to see if my car is running lean. I was told that it is getting extra hot (exhaust ping) because it is running lean. My fuel injectors check out okay, all at 12 or so ohm's. I need to know how to check the MAF, fuel pump, fuel pressure regulator, EGR system, etc. If anyone knows how to check these PLEEESE let me know. I am willing and most likely able to check these on my own and do the work but I need insight. I can't really find a Chilton's for the 92 SE because it mostly just speaks about the VQ motor. Anyone know how to do this stuff or can direct me to info, that would be great.
