Ok I cant seem to fing this anywhere on here.I have a 91 crx.I pulled a strong zc out of another crx and put it in mine.It ran great in his but for some reason now it falls on its face if I hit the trottle hard.If I slowly pull the throttle up it comes all the way up no problem but if I step on it on all it just bogs out.Any ideas?I cant find anything wrong anywhere.Thanx
