Question about 1994 Buick Regal Gran Sport

Open Question

My '94 gran sport 3800 has a miss in the motor. It occurs mostly at low rpm's - such as overdrive. It has received new plugs, wires - throttle components checked and ok, but can't get problem fixed. Also has a new fuel and air filter. Comes and goes. Any thoughts? Thank you, Brian Papak

It's probably the mass airflow sensor and/or oxygen sensors.

ENGINE IDLES ROUGH, BUT RUNS FINE WHILE DRIVING. My car is a 1995 Buick Regal Gran Sport with the 3800 series motor with 212000 miles. The rough idle tarted after driving through some muddy and wet roads


go the cheapest route. replace fuel filter and add SEAFOAM to tank of premiun fuel. replace filter before 500 miles. then add SEAFOAM to gas every 3000 miles to keep lines.engine,fuel pump, and emissions systems clean, ETHANOL problem number 3000

Check copper nut and stud on main connection to fuses on left inner fender. If need be use a metal washer to move nut to good thread area since thread gets worn due to soft metal.
