I was underneath my car today just getting ready to replace some parts and I noticed the PCM ground wire was spliced together. I forgot that I did that temp. to make it longer to get it away from my longtubes that I installed a year ago. I was thinking that maybe the problems I have been having with my car running terrible might be due to that. What would be some symptoms of a bad PCM gorund wire.

Hard to say. Fix it up and see if your problem persists.
