Whats the code that's showing up???? Did you research the code you have and make the repair. Clearing the codes won't do anything and eill keep coming back until the repair is done..

The spider fuel injector assembly are prone to failure and will cause misfiring and gasoline fouled spark plugs. If it's a fuel injector problem replace the entire spider assembly, if equipped, with the newer designed assembly. Don't replace individual injectors on this. HTH. -Jim
