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

I have a 99 Buick Regal, it hesitates and even stalls out. I had the oil and filters changed as well as the fuel filter. It is still hesitant and feels like it wants to dye. When I changed the fuel filter...


A combination of problems could be causing your hesitation/stall issue:
  1. Bad MAF (Mass Air Flow) sensor
  2. Bad TPS (Throttle Position Sensor)
Getting a free diagnostic test to pull codes will make narrowing down your problem a bit easier. Most chain auto parts stores will do a complimentary diagnostic test. The most common cause with a car that stalls when warm is the TPS. It controls your idling speed under all conditions. Even replacing the MAF alone doesn't always fix the problem although it may show up as being problematic. The 2 parts basically go hand in hand with your particular problem.

I would change your plugs and wires with original a/c delco factory wires and plugs.My buick did the same and got corrected with factory wires and plugs.I tried most of the after market and they didn't do the job.

1999 Silverado 5.3L hesitation ?


Filling it up with 92 octane will not help you so save your money to get other cool **** . If you want to put higher grade gas to the 89 ,but 87 will do the trick. Have you checked your pcv valve and hoses you might have a vaccum leak.

Car has hesitation at around 45 mph


Hi there,

You problem is most likely a bad spark plug wire or spark plug. I would start with the wires and then chenge the plugs. Most likely you have a wire shorting out under load.

I had the same problem on my 1999 century and it was cured after replacing the wires. My 1998 Regal GS was running rough and after I replaced the wires it runs great!

Good luck!
