Hi so I’m having a starting problem on a 1999 dodge Dakota 3.9l. The vehicle turns on when I press on the throttle but turns off if I let go. I’ve tried changing the IAC valve but it still occurs. Would anyone know what might be the problem?
Did you clean the throttle body IAC valve air passage?
Has the battery died or been replaced recently ? If so it will take a little while to relearn the idle parameters .
