Hey guys, my friend and I swapped in a JDM d15b into his 91 crx, we're pretty sure we got everything right, but when he goes to start it, it turns over fine and will actually fire but it will not actually run, so far we've changed plugs, played with timing, and just double checked everything. I'm usually pretty good at trouble shooting, but I just need some ideas on where to look. thanks.
