Re: 6.0 Swap Stumbling Idle
The exhaust has been fixed. No more leaks.
My tuner says that for some reason the PCM is not "seeing" the 12 volts at the o2 heaters..He has to program out the code.
Looks like I will be shipping out my computer.
Is there any reason that the truck would stumble quite a bit in reverse? It almost feels like it wants to stall. Pop it into neutral and it smooths out. It does not run like that at any other time.
