Question about Buick Regal

1 Answer

My 1991 Buick Regal cranks right up but lopes when in idle. Shuts off sometimes in drive and reverse. But still starts right up. Recently changed spark plugs and wires, pcv valve, MAP sensor. Car runs decent in park.

Hi, have to checked to make sure there is PCV flow? I see you put in a new valve, but did you check it with the engine running? The hose or port may be clogged.

Please see my tip at http://www.fixya.com/cars/r7427423-fix_poor_idle_high_idle_stalling_fuel . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

1991 Buick Ragal Custom 3.1 starts, then stalls immediately.


You need the exhaust converter so the O2 sensor can
work properly

It sounds as though the converter is blocked,as well
as the fuel trim, if that is correct term for an OBD1 System,
is not able to report back the oxygen in the failed converter

So the ecm can not provide the correct fuel mixture by
pulsing the injectors

I would also expect the timing chain to have a lot of slop
& possibly be off a couple teeth, from worm plastic gear
on cam

Have a 1995 Buick Regal 3.8L, after driving about 80-90 miles the engine stops, let it cool down and will start up and drive away, the coil packs been changed????


The crank position sensor on your 3800 sounds like it is going bad...this is sometimes difficult to show up on diagnostics...The part is about $35...location is near the main crank pulley...Hope this helps.

Hey ive got a 1991 buick regal 3.8L just a couple questions. #1 when the car has been running for awhile Idle or driving and then been shut off when it is re started in the near future before the genine...


Get the fuel pressure checked after you change the fuel filter. The magnet on the came gear will most likley need to be replaced. The timing cover will need to come off to do this. While you are in there replace the chain, cam thrust spring and tensioner too. The cars with 3800's will usually shut off when the crank sensor gets hot after driving. Cooling it with a spray bottle of water will sometimes make them run. As for you case when it acts up spay it and see if it clears up. If so replace it. What are the engine codes? reply

It is one of 2 things fuel pump or Crank Shaft Position Sensor. Best bet would be the Crank Shaft Sensor, and what that does is tell the computer where the crank is and when to fire the right plug at the right time
