Looking for answers for a buddy who swapped out a complete engine from a 14 800 Pro into a new bare tunnel/bulkhead ..the old sled was wrecked but ran fine . .did the swap and now it's running rough .. wont idle ..or idles high when it does ..throttle is kind of weird too. .doesn't necessarily respond exactly with the press of the flipper. . .pardon my ignorance here but just seeking some input .. on a motor swap does tps automatically have to be reset? . .or is there another component that's affected in a swap that needs adjustment? . .any help is appreciated .. thanks. .
