sorry I'm new to this forum but I have a 2005 Dakota 4.7 L. When the truck got to me it had had the IAC motor change the TPS sensor change and the mass air flow sensor changed along with the map sensor. The only way to get this truck to idle is to pull the plug off the intake behind the throttle body to induce a lean condition. I have checked everything with a scanner sprayed carburetor cleaner check with a smoke machine I have no intake leaks I have switched IAC motors have switched TPS sensors the only thing I can figure is I'm having a computer problem. if I could get some help that would be great but please do not contact this thread with a bunch of tests that I have already done.by the way there are no codes at all and this has been at two different shops before it got to my shop I have worked on Chrysler's for a long time and this one has baffled me.

Kind of a dumb question, was the battery unhooked for any of those jobs? And if so would it run if you applied throttle? I know on my truck if I unhook the battery It won't idle. I have to give it some gas to keep it running for about 15 minutes before it relearns how to idle.
