I believe mine is fried and i need to see if thats what the problem is, please help if you can, not sure what the hell is wrong with my car leading me to believe my pcm is bad, had car scanned again, code comming up saying that left 02 sensor is reading lean, car runs bad and misses, read outs on sensors are in the 15's-20's on one side (left side) and in the 900's on the other side...obviously something going on....changed both 02 sensors and it still runs like crap, unplugged battery and reset the codes and even after that the pcm will not clear codes out??? Please help if you know something or can swap PCM's with me, thanks

Are you sure you don't have that one O2 wire burned or grounding out somewhere. I'd check into all of that first before you are apt to toss your PCM. If anything try to extend the wires and swap sides. Like plug in the working plug in on the one side into the O2 on the non working side. And vise verse with the possibly non working wire and good working O2. Cover all those bases first, then if you still have persistant problems try swapping the PCM. Talk to Ion aka Madwolf and see if he can check your PCM for you. Good luck.

 

anyone else got any suggestions??? please help

 

Try to completely disconnect the O2's and reset the car. If that dosn't work then it must be something with the pcm if its still giveing wrong readings.
