Re: misfire...help
Any DTC codes?
Check for a dirt MAF and check the MAF connections.
Replace the plugs (this may fix the misfire too), go for a short drive, come home and pull the plugs. The plugs that look new are the cylinders misfiring.
If they are wet - you are getting fuel and no spark. Swap the coil to another cylinder and see if the misfire follows the coil. If so, this coil is defective. If not, check for pinched or damaged wiring in the engine bay.
If they are dry - you are not getting fuel. Check for dirty/clogged injectors. You may switch the injector to another cylinder to see if the misfire follows the injector. If not, check for pinched or damaged wiring in the engine bay.
