IfThrottle position sensor (TPS)
If it is not communicating with the ECM then the air fuel ratio can cause stumbling , lack of power etc because the computer cant tell how much fuel to command because it doesnt know how fast you are commanding the vehicle to go when you apply the gas pedal.

Have to plugs and wires been replaced according to the manual every 30/60K? Check for play in the distributor. Look in the throttle body with a light for oil on the intake floor, this would be a bad lower intake gasket. Make sure to use the factory recommended spark plugs, it only likes Champions.

Why is gear shift rough when accelerating quickly?


you need to let the RPMs drop down to match the speed you're going for the next gear, though this is less efficient than power shifting through.
Unless you're slipping the clutch to smooth out the gear change, yes, there will be a definite surge every time you grab a gear in a manual transmission vehicle. Most automatics will also shift noticeably harder at WOT.
For more sedate, "normal" driving, you can shift slower and feather the throttle a bit more to smooth out the gear changes, but when you're ******* the throttle as soon as the clutch engages, it's going to be a firm shift. I hope is ok.

I have a 97 buick lesabre with 3.8, at about 45-55mph it will stumble or hesitate when attempting to accelerate. Once it down shift and the revs get up it smooths out and pulls well


Replace plugs and wires at the same time to fix. It goes to lock up mode in the transmission at that speed and this is when you most notice a slight skip or miss.

PICKUP DOWN SHIFTS WHEN ACCELERATED


Attach a diagnostic computer to the leads on your engine.
Check the codes to confirm that the onboard computer is choosing to shift under the correct conditions.

Or, get your local Dodge dealer (before they go bankrupt) to run the computer-diagnosis.
