July 21, 2009I just got a '88 Dakota 3.9 2wd, automatic given to me. It runs and drives, but has issues. For starters, it seems to have a rough idle, and runs rough until you hit higher RPM's. If you run the RPM's up then let off of the accelerator it will die or almost dies. If you put it gear at idle it dies.
We hooked it up to a scanner and it read a couple codes, 88,FF, and AO. Don't know what those mean. Any help or suggestions would be great. We are pretty sure it needs a TPS.
