This dodge will not hold idle. It will run sluggishly with knocking/pinging down the highway and at speeds, but coming to a stop it will die. Replaced TPS and IAC, but IAC code still coming back from PCM. Pulled the MAP sensor off (still electric connected), and runs very very rough with black smoke as I hold the throttle open. Smoother with MAP fully connected but still dies.
I get codes:
12-battery (was disconnected)
14-MAP Sensor (only after I pulled wire connection out)
25- IAC (code flashing even with new part installed)
Vacuum lines look good, and connected well.
Any tips for next step? Flash PCM? I drove the truck 60 miles with new TPS and IAC.
have the same problem?
