Hi, I have done a 3sgte swap in my 90 celica. and now he start perfectly, idle OK but when I hit the gas too fast hey seem to missfire at 4000 rpm and when i slowly push on the gas i can take it to 5500 rpm but I have all ignition compenent new and i think am not suposed to have the rev limiter at 5500 so if some one can help i will be the happiest guy on earth lol
