These might help you out.............! having tranny problems out nowhere one day it would slip and not fully engage into gear until about 40 mph. after several weeks and a fluid filter and lucas trannyfix additive it still slipped . as a last result Idecided to check for blown fuses before a trip to the tranny shop.a 10a fuse feeding the transmissioncoolant fan was blown I believe that feeds the fan on the passenger side of the radiator, any way i replaced the 10a fuse the car worked like normal again I was later told that the computer will put certain parts of the car into a limp mode to stop catastrophic damage from say a overheated tranny. unfortunately most people will run to a repair shopfirst and get charged 1300.00 dollars for a 10a fuse ....you know it has happened more than we want to know!

92 buick park ave 3.8 sudden bad hesitation loss of power


This is likely a problem with the Mass Airflow sensor, it is a sensor that reads the amount of air going into the engine, when it fails it causes severs hesitation and power loss. Contact a local parts store or your GM dealer for a rebuilt one, the part is about $150.00. It is locate in the air intake hose to the engine.

I have a 1995 Buick Park Ave Ultra. The car has power but will not turn over. I was told by one shop that it might be the V.A.T.S. system and by another that it is the IGNITION CONTROL MODULE.


Make sure the battery cables are clean and tight on the battery. Check to see if the wires to the starter are tight. Try starting it in neutral to make sure the safety switch is being make. Also hold it up into park and try.

ECM switches from closed loop to open loop at idle after warmup


WHEN ENGINE GOES CLOSED LOOP TO OPEN LOOP.YOU HAVE A RICH FUEL MIXTURE.YOU HAVE A VACUUM LEAK.BY YOU HAVING ROUGH IDLING.AND A HIGH MILEAGE ENGINE I WOULD DO A COMPRESSION TEST OR CYLINDER LEAK DOWN. CHECK FOR LEAKING VALVES AND LOW COMPRESSION .THEY BOTH WILL CAUSE ENGINE TO IDLE ROUGH CAUSE MISFIRE.CAUSE OPEN LOOP CONTAMINATE HO2 SENSOR CAUSE A RICH FUEL MIXTURE.

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!
