cheeseburger Posted May 30, 2018 Share Posted May 30, 2018 Hello fine folks, My car misfires, nothing new for these cars. It started off on cylinders 3 and 4. I first swapped the coils between 1 and 3, no effect. I next tried swapping the injectors between 2 and 4 which caused the car to now misfire on ALL cylinders. I can smell unburnt fuel in the exhaust so now my question - What would cause a misfire on all cylinders after swapping two injectors around? The car also has an even worse idle than before. History - The engine was completely rebuilt 6k miles ago to replace a burnt exhaust valve. In the process, brand new OEM spark plugs were installed. The car ran great for about 3k miles until it started misfiring again. The idle gradually roughened up and it feels like the ECU is pulling timing again. I’m going to try getting romraider to take some logs to prove this but in the mean time, does anyone have suggestions?
