2004 mitsubishi endeavor cylinder 3 misfire TRIED EVERYTHING! PLEASE HELP
 

I keep pulling a cylinder 3 misfire code

i have changed coil twice. First one was an after market that overheated so i exchanged it and swapped it with a factory coil from another cylinder. Still a misfire.

New plugs , new coil boots, changed valve cover gasket and plug well seals. Swapped injectors from cylinder 3 and 4. Still a misfire.

Can anyone tell me what is roasting the coils on cylinder 3.

I read somewhere that someone had a bad ground on ground number 11 which was causing the coil to overheat. Can anyone shed light on this. Any help is greatly appreciated. Thank you in advance. I have pulled the intake plentum countless amount of times and cant pinpoint the problem.

Check the wiring harness, make sure there are no shorts :)

You can also do a compression test, and see if cylinder three is dead/mostly dead. That'd cause a misfire.
