Engine Mechanical problem
1993 Buick Lesabre 6 cyl Front Wheel Drive Automatic 125,00 miles

I have everything in the world checked on this car, it must have a ghost haunting it. I need to know how and where the throttle position sensor is? Where it is located and how to replace it? 1993 Buick Lesabre. replaced the fuel pump, fuel relay, fuel filter, coil packs, ignition module, crank shaft sensor. Some times it starts, sometimes it does'nt. I drove it for about 250 miles, it seemed like it was choking, then on the way to school today I was driving 55 miles an hour, and it died on me. The service engine light has been coming on, so yesterday I took it to O'Riellys and tested the computer. It said the throttle position sensor was low. Where is it located, and how do I replace it.

Hi
TPS is located on throttle body it is a little black box thing with three wire connector.Remove wires and mounting screws and replace with new make sure cam is positioned properly. Looks like the letter D
Hope this helps
