I have been having a weird engine problem. If I am sitting at a red light or stop sign some times the engine seems to have a miss to it, but its only does it when its in Drive or reverse, but not in neutral. I have new spark plugs, new spark plug wires, ran cleaner in my gas and changed the fuel filter, had someone tell me it might be a clogged injector but if it isn't doing it in neutral i don't think that is what it is.... I do have codes, O2 sensor and a knock sensor, I plan on doing the 02 around the 1st and the knock when I can get it into a shop. but I am at a lost. and when it does it you can feel it in the cab. I will try and get a video of it later.
