Asked in Oldsmobile Eighty-Eight
Why does my 1997 Oldsmobile 88 stall briefly while traveling at highway and low speeds?
Check for loose spark plug wires, make sure all electrical connections are tight and contacts are clean, Replace Throttle position sensor. When the sensor is failing, it makes the car feel like its loosing power at different speeds, the car for example may be just fine at 65mph but at 30 mph the car may seem to be missing, and that means replace the throttle position sensor, also change the exhaust manifold sensor. The 1997 olds are excellent cars,my neighbor has one with 195,000 miles on it and it runs just fine,excellent gas mpg for that size car too.
