Is the PROM seated properly?

Has it been messed with?

If you aren't static saavy, remove the PCM and take to a computer store or to someone who you know has a static wrist strap. You don't wanna fry it. Static is very high in my area right now. I zap almost everything....

I wish I can answer the question if the PROM has been messed with but I can't. I bought the car a few months ago from the original owner and ever sine then, the OBD shoots out that code 112 and the code 132 which is Knock Sensor Circuitary Failure. Where is the PROM located and what would be your best suggestion of what I should do.
thanks charlie
