May be fuel filter or air filter

Replace plugs and wires at the same time. An engine miss is more noticeable when the car is in fourth gear and converter is locked up, which is after 45mph. Carbon tracking on the plugs and wires can cause this.

It is very common for the torque converter clutch to begin slipping in these cars at 60-90k miles. It acts exactly like an engine miss. It happened to my 92 Bonneville, and after looking at all ignition items, a new torque converter fixed it. It did show a code when read at the Pontiac dealer. Also a 92 Bonneville has different transmission 4T60-E, it is enhanced with electronic controls and is controlled by the computer. The 90 has a 4T60 the transitional model from the old Hydramatic (formerly called the 440-T4 aka 4T60}. Parts are not the same in these transmissions. My 90 4T60 has over 298,000 miles on it.

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.
