well...its not so much of a hesitation as it is a shift up, shift down, shift up, shift down...all very quickly, which is what sounds like a trans problem to me. air filter was replaced, fuel injectors cleaned, and MAF cleaned all 500 miles go.
i was just browsing the transaxle section and i found
this post...which is why im sincerely hopeing that replacing the turbine speed sensor and refreshing the ATF does the trick...that long list scares me

... especially since he is describing almost exactly what is going on with my car.
my check engine light has been going on and off for a while now...usually it goes on after i fill up, and goes off at around half a tank...and its not a loose gascap. im tryin to get this resolved without having to pay to have the mechanics plug it in to a computer and then charge me 500 bucks.
thanks
