my truck recently had a misfires on 1 and 7 cylinders. I tried to clean the injectors with a fuel injection machine, but that did not work, so i replaced the two injectors and the plugs for those two cylinders. It worked for about 30 minutes and started to run really bad. it turned the engine light back on so i scanned it and it said that i had random misfires on 1,3,5, and 7 cylinders. I really do not know what else to do. the converter seems to be alright. the mass airflow sensor was changed out and that did not help, and there are no head gasket leaks.
