Seems to run just fine, but sometimes it seems like it’s missing and takes longer to shift; like power drops and trans just doesn’t shift. Deff noticeable on bridges (or likely hills for those of you not living on flat earth), but not at all times. It is way more prevalent with the AC on.
Giving it more throttle seems to smooth it out, sometimes letting off and letting it shift and throttle again will make it go away too; but only for that moment. It is random as in I can have a day where it happens here and there, or not happen for days. It always only lasts a couple of moments; otherwise runs fantastic.
So this is warm, under load, under light throttle or accelerating, conditions.
Plugs are fairly new. PCV is clean.
New Throttle Body (includes TPS, no IAC), ICM, Coils, EGR, EGR pipe.
No CAT; noticeable change when removed.
All fuel pressure tests were good.
No codes
A couple of months ago it ran hot (issue existed before) while driving though mountains and noticed the fan wasn't working, apparently the previous owner half assed a wire to batt. I noticed some puddling of antifreeze on the intake, behind the alt. I added water, kept running warm while in the area but not hot. Haven't had an issue since being back in flat Florida. How would this AF get in this location? Is this issue related somehow? Anyone have the diagram for the fan?
