Would a faulty PCM make my car stall intermittently, make the power (lights) flicker/surge at idle, make the fans come on at any given time, cause low poopy idle, and keep making my tps sensor go bad??? The car runs but stalls at least once everytime you drive it or let it sit in park or at a stop sign. Don't have any check engine codes. No "No Bus" reading from the pcm and I noticed that my spark advance seems to be a little lower than it should.
Any one?????
Need help ASAP.

Check your battery for charge, battery cables then your alternator for correct charging.

also check for loose ground wires. If you had mechanical work done to your car prior to the problem or body repair to an area of your car where there are ground wires - look there. I once had a headlight ground wire screw that was just a little loose and it would cause the car to stall, idle roughly, and over-all run nasty and it was intermittent.

I agree with these guys! It's not common for a PCM to go bad. Autozone will test the battery and your chargeing system for nothing. Good Luck!

the battery is new and the alternator runs a constant 13.8. I will check the ground wires, thanks for the input.
Also, is the fuel pump supposed to shut off if the ground wire is not connected to it? I pulled it off just to see what it would do and it just stayed on. Is this weird or ok?
