My thoughts last summer ran more along the lines of CPS flaking at high temps. From what I have read though, CPS failures tend to manifest as not starting. Are there other failure modes for CPS?
There is a slight roughness to the engine when this is happening under acceleration. It could be misfires, but it is so subtle I am not sure. Plus T7 compensates for things so well, it might be masking a misfire.
So if we look at the area in front of the engine where the heat is, We have the CPS, the MAF, the bypass valve and associated sensors, and ?????
We all know the dealer isn't going to replace anything without a clear failure. So how can I deduce which component it is?
BEFORE I FORGET...
I REALLY appreciate the discussion on this. Multiple heads are definitely better than one.
