Re: Spark Plug Helpp

You don't have to take the fuel rails off. Just remove the coil packs and the plugs can be removed. Make sure you blow any debris out of the holes before pulling the plugs. Also when installing them torque them properly. Too tight and they can strip out when the cyl, head stretches, too loose and they can blow out.

Re: Spark Plug Helpp

You could pull one injector wire at a time until you find one that doesn't change the RPM or miss. That will probably have a bad coil pack. There could be more. Then change that coil with one that made a difference in the RPM to see if the miss changes to the other cyl. to prove it is the coil for sure. That would prove that the coil needs replacing.
