Default Hesitation

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.

What do you guys think it is? Opti-crap?

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.

Good luck.

CAGS=computer assisted gear shifting (it's the 1st to 4th thing, you know the one for fuel economy...)

Sorry my name's not Frank... :bb

all six speeds did and still do have it.

Under certain conditions it will kick in, others it won't. Depends on operating temp,throttle position etc.

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..

CAGS is still functional but it only happens when the car is hot.
When the car is cold she runs like a horse (300 horses).

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!
