      Re: Really Strange Knock

      Here's a new issue. It is still showing 22.4 KR. when I disconnect the MAP sensor knock is instantly gone. Now when I'm WOT above 4k rpm the motor feels like it is misfiring. I had a scan tool on it and the whole time I had 0 misfires..... Thoughts? Replace coils? Plugs?? I pulled the MAP sensor and the gas is no longer there. I also removed PCM connections and cleaned them.

            I have a similar problem going on and I have found it to be an exhaust leak between the manifolds and block. check that while you're doing all this

              I checked both sides and they seemed torqued to correct specs, I'll check more tomorrow. A scan is on my last post in this forum:
