I am getting a real bad backfire at around 4,500 RPMs. I was told to plug the hose running from the top of the headers that runs to the airbox.
I have located a Gray hose (the only hose) running into the bottom of the airbox...is this the correct hose to block off? It is about 6 inches long and runs into a plastic piece above the headers.
I want to be certain before I RTV this plug into the hose.
Thanks
