Re: No Power Under 3k Rpms

I had the same problem when i swaped my prelude from an h23 to a h22, the problem for me was that i was useing the h23 injectors on the h22 so it was causing it to bogg under 3-4k rpms. then i switched to the h22 injectors and it worked great. might be somthing you could look at. hope this helps
