The engine in my suv is misfiring. I tried putting injection cleaner in the fuel and that changed nothing. The engine light came on about 6 months ago, so i gave it a tuneup and had the codes reset. The truck run good til about 3 weeks ago and the same problem arose once again. Misfiring and the engine light is back on, also the more i excelarate the worse it gets. The code that comes up eveytime is #4 cyclinder misfiring or dead. Is this an injector going bad? Can you please help me as to how to fix this problem.
