Long story short = problems with normal/warm weather
no problem when well below freezing.
Last summer my car started hesitating during accelration.. it felt almost like someone was sitting in the passenger seat turning the A/C on and off repeatedly. It gets very annoying but doesn't seem to do it if you floor it, only during regular driving.
Since it's been winter weather (well below freezing) the problem has gone away!
The last week it has been above freezing and the problem has come back.
I've tried all the obvious things like clean the CAI
, clean the MAF, reset the CPU etc. Does anyone have any ideas what it may be.
