Re: 56.3 runs rough when cold & WOT
Just so we are clear i am saying to pull the 4 torx bolts out of the maf and pull it apart into its 3 parts. And I don't believe i've seen it mentioned but what about IAT readings? MAP reading? How dirty is your throttle body, iac pintle and iac bore? could have enuf gunk in it to be hanging up a bit.
