Pheno

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...
