Question about 1999 Buick Regal

1 Answer

1999 Buick Regal GS supercharger is hesitating at 30-40 mph while driving at a steady speed after transmission has changed into high gear. It is more noticeable while driving up a hill or incline than on level ground. It appears to be pulsing in and out of power during this period.

1999 Regal GS -stalls, starting trouble, won't shift now


the batt is suspect...take it to autozone, or other place, they'll check it out free......the shifting out of park is a seperate issue, the pawl for the steering/shifter is not working properly....did you notice if the steering wheel would turn when the shifter is stuck?....probably not....when this happens try to turn the wheel back and forth-not hard but not gently- a little graphite dust sprayed in there would help.......hope this helps you out

Is a '94 Buick Regal GS front or rear-wheel drive?


Better still find a peugeot 307 or a ford focus all with manual transmission,and a high fuel economy so the rag heads can drink crude and live in the desert and ride camels

Check the idle air control as it is operating when you start the car and after the car warms up it is out of the system.

1994 Buick Regal "shudders" while driving/ won't always up-shift


It is a 24 year old vehicle (made in 94), it probably needs to retire :>)

Take it to a transmission specialist rather than a normal garage, as it sounds like a sensor problem. It may also be rubber mountings that have perished, and the engine and transmission are only partially mounted to the chassis.

1999 Buick Regal hesitation while driving


most likely it is not actually a misfire it is the overdrive/TCC solenoid kicking on and off, it is a common GM transmission issue
