I left work and stopped to fill up at the gas station. Shut my 1993 explorer off and filled up. When I started to leave, it barely started and was running terrible. I pulled each plug wire to see if there was any notice change in idle. Looking under the hood, the back left cylinder made a different noise when unplugged. The rest didn't make much difference. I drove it home and had to let off the throttle every time to get it to shift into overdrive.
The next day, I fired it up and it ran somewhat ok. Drove it around and it still was not right but it was running better. Shut it off and restarted. Ran worse than the day before.
I pulled the codes.
Thanks to the explorerforum, I looked up all the codes. 513 stuck out the most. The couple of threads I read through had information saying the pcm has capacitors that have failed. I was fortunate enough to have a parts explorer sitting there with the right pcm in it. Swapped them out and it solved the issue. So far it is running great.
I wanted to share this experience so if anyone else gets codes like these, they have another thread to read to help.
Photo of good pcm. Capacitors look good.
Bad PCM with bad leaking capacitors. One leg of the capacitor wasn't even making contact anymore
