My 1994 tends to hesitate when the engine is hot (after about 30 minutes). When the engine is cold the car has so much power that I could easily do the 1st gear to 4th gear shift but when the engine is hot the car bogs down. When i try to shift 1st to 4th gear the car will jerk a couple of times.
When the car is hot I can not do a 2nd gear rolling stop it also bogs down.
I would lean towards ECM. Are you getting any error codes? When my '92 went, I got error codes saying I had bad grounds. When it heated up it ran like a dog. Replaced the ECM (after no less than 100 hours diagnosing the problem) and it went away. The ground points inside the unit were failing when it got hot.
I ran into this problem for the first time yesterday....I was like :eek: :confused: :nonod: :cuss If it is the ECM....will I need to change the box? What will that cost? This seems to be a fairly common problem...should ask in the tech/perf, might get more opinions

It cost me $150 from the dealer, and it's an exchange item. They rebuild 'em. You'll need to give them the number's from the box..
I might be way off base here..but didn't somebody mention something about a certain sensor that could be moved from its current location to help prevent that sensor from getting false readings from too much engine heat? Could that help?
My reason for even mentioning this is he stated that it only does it after she gets hot!
