Sounds like it could be your ISC motor, idle speed control motor in what maintance your idle speed, sit on the throttle body, held on with two small bolt's, remove it and clean it with carb. spray, if that don't take care of it, might need replacing.

    IF plug wires are bad, or put on wrong, will run with a bad engine misfire, if no misfire, check ISC motor.

My 1993 buick century stalls when i stop at a light or stop sign after i restart it it backfires multiple time before i can gain speed


I have a feeling your fuel pump is on its way out...but start by changing your fuel filter first, should be under $20....ie..not enough fuel getting through..

My car is sputtering and a spark plug came out


I have a 1990 Buick Century with 3.3 v6. My car would sputter and the check engine light would come on and off while driving and the car would die when I came to a stop and tried to take off. I noticed my cooling fan turning on and off even when the car was not up to temp, and that is when the check engine light would come on. I changed the temp sensor and all is well.

Ok i recently changed spark plugs on my 1994 buick skylark. when i was done changing plugs i started car up and smelled strong exhaust smell. so i checked the plugs wires and found out that when i pulled...


Did you mean coil the 1994 3.1 did not use a distributor , sounds like a bad coil pack and cylinders #3 and #6 do use the same coil. I would also check 3 and 6 plug wires this system is a waste spark design meaning when # 3 coil fires it is supposed to go through #3 plug wire , through #3 plug ( ground) through the engine block through the #6 plug then through the #6 wire then back to the coil, Then when #6 fires it works the opposite way, so in theory you could have one bad wire affecting 2 cylinders .....
