Im looking all over for help on this. I just bought a 93 civic 4 dr, and it is slower than hell. I did a tuneup, wires, plugs, oil, lube ect.... She wants to go but it isnt working. Ive put a new muffler, dist cap on as well. I cant find any problems that could cause it. I have tried to put on an open air intake and that seems to make it worse. Ive been hearing they are a pain in the butt to get more power out of it but I know there is a way, if anyone has any suggestions im open and could really use the help...
