In a nutshell:
On a warm engine that is turned off; unplug the MAF sensor. (while leaving the actual sensor in the intake pipe). Turn on the car, let it run for 10 full minutes (set a timer on your phone). Turn it off, plug back in the MAF.
On the next cold start, it should be fixed.
It seems over time the DME idle learning goes bad and this is a method to reset the idle parameters.
yes exactly.

thanks for the information I have given it a try and will see what tomorrow morning brings. I can say after doing this and clearing the codes the cars engine idle is even smoother now than it was. I have read through so many post tonight and many had the same thought process it normal, its HPFP, and replace a bunch of parts. Only 1 or 2 made any mention of the MAF sensor and your information is by far the best and most logical process thank you
