I recently converted my car over to an OBD1 PCM with tuning from madz28. My SES light is still on. Tracked it down to the MAF sensor. Anyone know how i could test the sensor to see if it is bad or test the wiring to see if i have a short somewhere? I heard there was a MAF fuse but i checked and all of my fuses are ok.

 

Sometimes the engine sensor fuse will blow and throw that code. May look at the wiring to the MAF sensor. I believe the pink wire has some problems sometimes of losing power. May need to do a search in LT1 tech though to make sure what color wires are supposed to do what.
