I have a 1992 buick lesabre limited and it has lately been acting up. when you press on the accelerator it surges and makes it hard to get up a hill. It also stalls when you are idling and not moving for example waiting at a traffic light. The service engine soon light is almost always on and I haven't been driving it because it isn't safe or dependable on the road. If you have any info on how I can fix it please tell me. Thanks

I purchased a 94 with 140k on it a few months back. It's a FL car and in super shape. But it has a funny misfire, sometimes very subtle and sometimes very hard, almost a "bucking", for lack of a better term, and the engine light comes on but will go back off if I shut the car off and start it again. It's even begun stalling every now and then at a traffic light but always starts right back up like nothing happened. It happens at different times; when the engine is cold, when it's hot, when I'm cruising down the highway, when I'm driving in the city, when I accelerate, when I'm stopped at a light. I can't connect the misfire with any given driving condition. I've replaced the plugs and wires, air and fuel filters, changed the oil, repaired a leaking vacuum line to the fuel pressure regulator and replaced the crank sensor. I've run a bottle of dry gas through the tank, thinking that maybe some condensation built up from sitting while it was for sale. And a bottle of fuel injector cleaner as well. Nothing has seemed to make the slightest bit of difference. Any ideas would be greatly appreciated.

Replying to: dshepherd3 (May 14, 2006 10:48 am) I have to apologize, I left out the part about the scan. A very close friend of mine owns and runs a shop where I have my work done, or do myself if the job is not too hard. The day I brought it in to replace the crank sensor, about 2 months ago, he tried to read the code and could not. I guess in 94 GM installed a newer type of connection in the car where you plug in the reader (under the dash) however the newer reader won't connect to the car. I mean it plugs in of course but the reader doesn't acknowledge the vehicle. We searched for the older style reader connection under the dash and under the hood and could not find one.

| I am working on 1995 Buick LeSabre. It will run ok for awhile, but then it stalls and is hard to start. Recent work on it was a normal tune up, Spark plugs, wires, gas filter, and air filter. I even dropped the gas tank and cleaned it out. Also, when I rev the engine, I can not get it to go over 4000 rpms. It seems like it gets too much gass or air and starts to choke out until it gets back down to 3500 rpms. I have also cleaned out the port injectors. The check engine light comes on, but Autozone states that there computer reader only does 1996 and newer vehicles. Any ideas on the problem?? Any help is appreciated!! | |
