One or more fuel injectors may become stuck closed causing an engine misfire  and the Check Engine Light to illuminate. Our technicians tell us that this problem can be caused by some fuel additives. There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.

    My 99 gmc yukon recently started acting up on my way home from work. I barely made it home. When I have foot on gas ok when I take it off it starts shaking alot and hesitates. I used a scanner and found codes misfire codes maf sensor and o2 sensor bank 2 sensor 1 I changed the maf sensor changed o2 sensor and also did a complete tune up and also changed the fuel filter plugs wires dist cap eveything put in new gas. Still acting up took to local shop and they could not figure out the problem now my only choice is to take to dealer.
