i have a b18a1 in a crx hf. and i finally got it running and i took it out. i must say it moves out nicely but once in a while it miss fires around 5,000 rpm's. what caouold be causeing this? i think my spark plug wires my be messed up inside or i my have a slght gap between my exhaust manifold and down pipe would this cause it to miss fire? any help would be great thanks!!1

 

maybe it needs a tuneup....
