Question about 1989 Buick Park Avenue

1989 Buick Park Avenue dies when in gear

Yesterday the car was idling really high and seemed to take off when I would let off the brake. Last night I tried to start it and it was running really rough, like the idle was very low and it was barely running. Once I put it in gear it sputtered and shut off. I attempted to start it a few more times and nothing. Then it did start but ran very rough and shut off when in drive. Any ideas on what it could be?

SOURCE: I have a 1991 Buick Park Avenue. Runs rough in

Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.
To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: Engine shakes when accelerates, lost power, Buick Park Avenue

Look for a bad coil pack. If you have the bank of three coils on the front passenger side of the motor, it is possible that one of them is going bad. This can be an intermittent problem since it failure is frequently heat related, and may not show up until the car is all heated up. It is simple enough to change one of these if you can figure out which one it is. There is a little device ( Spark detector) that can sense the sparks inside the wires. Get one and hold it close to each wire... away from the coils. The wire, that does not make the spark detector light up...is coming from the bad coil. (It is also possible that a spark plug wire is bad instead.) Good luck. Chip

SOURCE: 1995 Buick Park Ave. Brake light remains ON and chimes on driving

The problem is the car think the park brake is on (intermittently). I would check the park brake switch, perhaps it's loose, or perhaps the park brake is pushed down to the first "click" spot. Also check the wiring connection to the switch, and the wiring nearby. Good luck!

It sounds like you have a vacuum leak or intake gaskets leaking. Try this. Start the engine and let it reach the idle it want to go to. Get you a can of Brake Clean and spray it around the intake manifold (it on the top center of the engine, you may have to removed a plastic cover) If the engine idle changes up or down then the intake gaskets are leaking hence your vacuum leak. I hope this will help you.

sounds familiar, I had that problem one night, started my car and the lights that are automatic didn`t come on. Well I started to check things I realized my emergency brake pedal wasn`t coming all the way up so I put the emergency brake on and then releast it and helped it come up with my foot and lo and behold my lights came on. sort of a safety feature to prevent you from putting your car in gear and going.
