My 1996 Buick has a hesitation from a standing start. If you "blip" the throttle, sometimes it will stall. Makes no difference if it's cold or warm. When parked, if you give it a hard accel it act's like it is starving for gas. It doesn't rev like a engine should. Being that I just bought this car recently I have no history on it. I changed the fuel filter as it was only driven about 1,000 miles in the last year. Ironically, when I put in a can of fuel injector cleaner, it ran just fine. Adding another can on the next tank fill did nothing. It idle's just fine and run's just fine with no "service engine" light ever coming on. The car has 52,000 miles on it and I do believe it was in a wreck at one time with front end damage. I did find a set screw at the base of the accelerator linkage, (a screw in the center of a 8mm nut) so I kicked the idle up with that but then the "service engine" light came on shortly after that and the light went out again after I put the screw back to it's original position. AutoZone hooked up a scanner but the dude screwed it up I think and never got a code out of it. Perhaps I need to do a reest on the ECM? If I pull the PCM fuse, do you do it with the key on or off to clear things? Any other suggestions for me to look for? Thanks
