This has me stumped. I have replaced the plugs, wires, swapped the coils, replaced the fuel injector, ran a compression test (all cylinders within 10lbs of each other.) 115 to 125, checked the injector electrical system with a noid light, the obd2 code scanner says all systems working fine. ANY HELP WOULD BE GREATLY APPRECIATED!!!!!!! PLEASE THIS IS DRIVING ME INSANE:banghead: !
