97 Dakota 3.9L 2wd auto
rough idling issue: I cleaned the IAC carefully and replaced the temp sensor, wires and ignition coil. When truck is cold it stalls immediately when put into Drive unless the accelerator is depressed. When warmed up (90-100), it will stall out eventually while idling in Drive. Never stalls out in Neutral or Park. If I shift to Reverse it will sometimes stall out as well.
issue #2 : no comms with ECM, cannot run scanner to get any codes. Today I removed all 3 connectors at the ECM, checked continuity and voltages (all good) with connector port inside truck, replaced the connectors and the check engine light disappeared. That might be a good sign, however still cannot run a scan.
Drove 25 miles afterwards, check engine light did not return, vehicle performing a little better but will still stall out in Drive while idling.
have the same problem?
