- What's the worst that could happen?
This is the thing that makes it all go.
I recently had a bunch of different issues with rough and varying rpm/idle. Truck would lose all power and stall if I pressed too hard on the accelerator as in trying to hit passing gear. I did all the usual things like checking for vacuum leaks, checking the IAC, the thermostat and temperature sensor, throttle position, etc.
Finally pulled the PCM to check the capacitors as has been mentioned as a problem area that can cause all kinds of havoc. When I pulled it, I found that the capacitors were in pretty good condition -- really good considering they're over 25 years old. I did not replace them but I know I may have to at some point in the future per recommendations by RonD and others..
What I did do was clean the crap out of the ground wires from the PCM to the fender wall. The connection was in pretty bad shape -- green and crustry.
Turns out that that simple ten minute job appears to have solved the problems I was having. The ground connection sits right below the cruise control servo (if you have cruise), just above and forward of where the PCM sticks out of the firewall.
Lesson ;earned and am posting here to remind y'all. Thanks to RonD fro all the help with my troubles.
