EFI-IV starting
Are these trucks suppose to start without any accelerator depressing while key turning?
My truck starts and dies several times before it eventually gets going. And then it's rough.
Runs smooth and steady with the spout off. Thought that if there was a vacuum leak it would run rough with the spout off as well.
And it's not the IAC because I replaced that with no improvement.
Someone suggested replacing the PCM.
