1995 Buick Regal Q&A
1995 Buick Regal Question: My buick starts chugging after it shifts into overdrive,then it smooths out.
If it is a jerking action most likely engine misfire, have it scaned for codes. Most likely a plug wire but scanner can pinpoint which cylinder so problem can be found more easily. Now if it is a fast shutter or like a vibration, may be a torque converter problem. - pushrod
