??ECM?? 2003 dodge 3500
Hey Folks, just joined today, wish I had done this long time ago. I've been told I should find a used ecm and try to see if problem goes away. I have had this in and out of shops, and the problem is still there.
Truck is early 2003 Dodge 3500 with cummins 5.9l diesel..
Problem: Sometimes when I start the truck and start to drive, the rpm will go to 2000 rpms and not go any futher no matter what I do. I have to pull over, turn the engine off, wait about 20 - 30 seconds and start engine again, sometimes it takes and works fine, and others I will have to do it 2-3 times. There is no pattern what so ever as to when it will do this. Once it accelerates past 2000 rpms, it works fine until I turn the engine off, then all bets are off if it will hang or not. Any help will certainly be appreciated...
