The first two stop signs it hesitates a little bit after that it is usually ok.
I did the code scan and it reveled two codes. 1) TPS 2) MAP Sensor. I checked the TPS it is perfect, could it be the map sensor?

Any ideas what could be causing this? I have done a full tune-up.

Does it have any type of Air Temp scensor on it that may be bad. My 93 Merc Marquis has a similar problem. Hesitation bad when cold. Turned out that there was a vacum leak that was real tiny until one day a rubble elbow jsut calapsed on its self. fixed that and it runs fine now. Just SOOOO many things it could be w/todays cars and the computer stuff.
