Okay here it is, two days ago I noticed a new tapping sound, failrly loud too. This morning it was much more pronounced, it is in the front of the engine, and the rythm matches the feel of the pulse on the foward most injector(which is like 100 times harder of a pulse feeling than any other fuel line). This afternoon it was even louder and on start up the truck had a puff of smoke. So I am guessing that that injector is calling it quits, or am I wrong? Oil level is just fine, no noticeable difference in everyday driving. If I am right, best plan of action? new factory,? dealership involvement? aftermarket full set? Sorry to ask so many at one time but I REALLY need yalls thoughts on this. Or, best case am I wrong in matching the sound with the feel? Thanks in advance yall.

If its under warranty put it back to stock prog and take it in for repair. They go all the time. Mine were fixed without question.
