:wave: Hello everybody. After many long days of waiting, my account has been activated. Now onto things that you actually care about. I know it's probably been talked about on another thread, but I got tired of looking for anything that's more specific to me. I recently traveled to Minnesota from Indiana to get a green '91 SHO+. Aside from a bad throttle position sensor, the thing was a dream on the drive back. And as soon as I got home, I swapped the TPS with one from a dead gold/mocha '91 I have, then it was perfect. About four weeks ago I'd notice the engine would periodically jump when around 3,000 RPM, but that was about it. That developed into rough idle, and then that turned into dying all of the time. I started it up today, and it ran fine. It just goes in and out all of the time. I pulled the codes, but misplaced the piece of paper, otherwise I'd put those up. I checked the pressure at the injectors, and it's getting plenty of gas, so it isn't the pump or the filter. I've changed the DIS module and the coil pack, so that leaves the CPS and the other dealie-majig, right? Or is there something else that would cause the ignition to go screwy every now and then? I'm frustrated and don't want to resort to a "Mopar Repair Kit." Y'know, a grenade?! :bonk:

You need to find out what those codes were, because the car knows what is going on, and the codes will tell you what that is. How are the plug wells, are they full of oil? I would look at the condition of the plugs and wires. Also the IAB might have something to do with what is going on.
