I have a 1986 Honda Prelude SI and it surges while you're driving it's not when u r idli n g. It's when you're driving and I've changed the fuel injectors and the fuel regulator and it still does it when you go into each gear chugs back and forth it surges and I can't get it to stop and I was wondering if anybody can help me on this. It also back fires alot

 

not many people here know much about the 2nd generation prelude motor. best bet is to check out preludepower.com
