Dealer

[CraigJones]

I have brought my truck in two times so far because I know I have a bad injector(s). But they will not look into it any further. They did a pressure test the first time and the said they where all in spec. Today they said they adjusted the valves which didn't do anything. This is frustrating to say the least. Its not a loud knock all the time but when I'm on the highway I can still hear when I just let off the fuel pedal. I tried putting on a quadbox about two months ago and I had such a bad knock I took it right out. When the box is on my truck you can hear a loud knock. Its not the quadbox because I tried another one from my friends truck and it works fine on his. This is really driving me crazy,I want to bomb my truck and I can't because I know something is wrong. Anybody know any bomb dealerships up hear in the northeast ?
