Why would a 1987 Buick LeSabre 'hiccup' and jerk while accelerating?
Hey Amber==It is probably in need of a tune up. Goodluck, Joe there could be a few things wrong with it. most likely a bad throttle position sensor or a bad MAP/MAF sensor. however, only a mechanic will be able to tell for sure what it is. my best advice to you as a mechanic is take it to the shop to have it looked at. Consider looking at the Crankshaft Position Sensor (CPS) as well.
