Question about 1991 Buick LeSabre

1 Answer

A little transmision hesatation.

When im driving, when i need to speed up to pass somone my trans mission hesatates. i hit the gas one, two, three seconds later my Buick will take off strong.
Could this be the throtle position sensor or maybe the cables that go from the throtle body to the tranny need adjusted?
I dont think the transmision is slipping buy im not for sure.

Also, i would like to build it up a little. A rebuilt engine with duel 2 1/2 inch exaust pipes. rebuild transmission. and a turbo charger, if it will fit.
I want to keep it looking stock, i just want the mechanics of the car to be "hoped-up'' a little. but not enough to affect my gas milage!
Do you know where i could find out if a trubo can be installed with the engine computer? and is it possible to run dule exaust?
i think id probably have to install another cat. converter.
Please e-mail me at

Bear in mind that for the transmission to work properly, the engine needs to be running at optimum specs. If the engine is even just a tiny bit off these, the transmission will not respond properly. For instance, a partially clogged air filter will cause these symptoms.A project such as what you're wanting to do with modifying your car Will set you back about 3000 dollars and Will affect your gas mileage, to the point that it is economically not feasible..accordianman

first of all the early 95's were OBD1 so if your jeep was made before june of 95 IIRC you will have an OBD1 diagnostic system, and it is different then the OBD2 plug the guy was looking for. It could be a bad MAF sensor, a plugged cat, a bad injector, a timing issue. You need to go to the right place to get it checked out. Phone around to the shops and see what they charge to run a diagnostic on your jeep. A good place will usually run it for free, or cheap. They will also give you competitve prices on the repair needed. Also they should let you know if they find anything else wrong, and ask before repairing it. Phone the BBB for a list of reputible shops in your area.
