since we purchased this vehicle new (in May 2001), during the hottest summer days, it seems to have a severe hesitation when trying to take off, or merge into traffic. if you do a google search, i'll bet you'll find me posting in here about this problem back in 2001 or 2002. well the dealers i've taken it to have done all (or said they've done all) of the tsb's available and it has not helped. this summer, about 3-4 weeks ago, i felt the hesitation again. when i asked my wife how long it had been doing this she said; "it never stopped," i asked her why she hadn't told me before and .....well nevermind, needless to say, i'm having a hard time getting the dealer to duplicate the problem.
the best way i can describe it is: on a real hot day (98 or above) when you place it in drive (i don't recall it ever happening in reverse), it just will not go...i mean it is rolling forward slowly, but the engine is not responding the the accelerator pedal being mashed to the ground. (no rpm's, no vibration, nothing) finally after about 2-4 seconds it takes off. i don't know what else to do. right now the dealer has a "vehicle black box" attached to it, and we're supposed to press a button whenever the problem occurs again. this computer/black box will take a picture of the computer codes, 30 seconds before and after the event.
what do you think?
