oh, and when i slightly rev the engine from the engine bay i hear a weird almost clicking noise from what i believe is the EGR valve, i can't really describe it but it sounds just like the noise a metal detector makes but without the high pitched noise. You know how the metal detectors that you walk around with kinda like a weed wacker sound? well, it is just like that, but like i said, no high pitch noise that it makes when you found somethin. Ok i just read what i put back to my self and that was the dumbest comparison i have ever made in my life but, it's all i could think of lol, anyway, someone help a brotha out please
