If the engine is not spitting or sputtering, the plugs are fine. If they were fouled, the engine would not run well at all. Probably just the fuel is stale. Today's fuels don't hold up in the tank like they use to do. Once you get that fuel run out and put some fresh fuel in the bike it should run like it always did before the surgery.

Won't start


Check the fuel injectors, with the key on one side of the two wire connector will have battery voltage, if none is present then check the ECM fuses in the underhood fuel box.

My 2001 alero shakes at stop lights dies from time to time and when the light turns green it looses powers sort of like a drag



  • Sounds like you have some really fouled plugs. I would start with a tune up or plugs and wire at least. When your plugs, or even one plug, get fouled it creates a misfire and when at a stop light etc the cars will shake a bit and almost feel like it wants to **** a bit. Then when taking off it putters and lacks proper accelerations abilities.

  • Also make sure to use good gas as bad gas will cause some sluggishness too.

  • Hope this helps.

Hi, it sounds like you may have a plugged fuel filter, causing the described issues. This is the first area I would inspect.Good luck...Coop
