Hello
I'm experiencing a power loss at 4000 rpm. I figure its somehow linked to the butterfly controller that opens the other 2 runners at 4k. I checked for vaccuum leaks, checked for loose electrical connections and its not throwing a code. Drives fine until i reach 4k, if i shift before 4k i wont notice the problem but... whats the fun in that? Anyone have any ideas?
