So i'v been having issues with the car misfireing , Changed the coil pack , the leads , the plugs , the fuel pressure reg and even and injector. Still she misfires on 3! A compresstion test cleared all cylinders of any issues , iv also changed some coolant temp sensor and I feel there is something else im forgetting. Does anyone have any ideas? I'm thinking to change the tank sender unit to see if this clears the isusse. Prior to any of these repairs the car would run rough on idle misfireing all over the place , you could sit and watch the rev counter bouncing , so after changing the usual suspects the issue seem to clear but then the misfire returened , so I went down the injector route to no avail. I am really running out of ideas and the will to fix this dam car , so please any help would be greatly appriceated.
