Question about 1995 Buick LeSabre
Lately, our car has been having episodes of bucking or surging when we are driving it....it seems to be worse when the engine is under greater load, like traveling above 50 mph, going uphill, or when AC is running. Lately, the engine has also started dying, usually at lower speeds (slowing to stop or taking off from stop), but happened a couple of times when driving down the road at 35 mph. The problem can last for a second or two, but sometimes for 5 min. or longer. But then car recovers itself and can drive for hours without the problem happening. Mech's are stumped...can anyone help ID this problem and get our otherwise great car back to its old self? THANKS!
As odd as this may sound its a power (electrical) problem check the battery the alternator and the cable coming off of the alternator my car does this when there is not enough current to (something?) lol.... so check all those thigs and report back

I posted the original problem...after a few different tries, we discovered that it was the ECM (the main computer). Once replaced, the car has not had a problem since!

Does this happen when the car has a full tank of gas? or is it 1/2 ?to 1/4 tank ?it could be the fuel pump is over heating or a bad wire connected to one of the ignition components or even the mass air sensor. check the wiring make sure it is secure and corrosion free but also make sure your fuel pump isnt over heating try and look at your gas gauge next time it happens
