20 Most Recent 1991 Buick Park Avenue Questions & Answers


i just came across this problem myself the other day. i have a 91 buick park avenue that sometimes won't start. i checked several things out like cable connections and coil pack etc. etc. come to find out it was the wiring that came off the coil pack and connects to the crank sensor. the wiring that ran over top of the water pump had finally heated up so bad the coating on the wires had melted and when the engine got hot enough the wires would come in contact and send false signals to the computer not letting it start. after the car cools down and the wires contract it would start. so check the wires from the coil pack to the crank sensor to make sure the wires are not melted together.

Look in the trunk on the ant side and pull back the the felt and you will see where it connects and disconnects. You may have a broken antenna lead. At the bottom of all electronic antennas is a plastic lead that fits in the motor to wind the antenna up or down. See if that is still attached or broken. If the motor is still good you only need to replace the stem, but if there is no life to the motor then you will have to replace it.

Cant really see why replacing a crank snsor would help a car crank, although i understand why it would start when cranking.
Maybe you have a duff battery or a failure on your charging system.
I would strongly suggest using a diagnostic computer to realise the correct area of fault before guessing and spending lots of money on the wrong parts.

if car shuts off while driving it could be a bad crank sensor. a bad crank sensor will shut car off while driving, then it will not start for about 10 minutes, when it starts it runs fine until it goofs up again. the popping could be the sensor for it controls timing along with the cam sensor.

Sound like the cam sensor is loose and not seated properly or has something foreign on it.

This would not be caused by the calipers, it would be the Master cylinder or the ABS hydraulic control unit.

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.

A chilton manual will give you a diagram specially if you have a twilight sentinel system. You can get one at auto parts stores or online.

I would seriously have a cat put back on you need that back pressure and have the O2 sensors replaced. Sounds like it may be time for a major tune up
