Well I bought the civic w/ the swap already done. It only had one problem and that was the front motor mount being loose. But didnt really have a problem with it. Ever since I hit 120mph in it. My fuel pressure was rising slowly every day. It went from 40 psi to 80 psi. Which it sits at now. It misfires underload and when ever I shift normally. When I would want to race or something (snach 2nd gear at 7000rpms). The whole front end would shake back and forth violently(pisses me off). Now I just found out my motor mounts are worn out. So Im goin to replace those. But I still have that misfiring at idle sometimes and always misfires underload. I also smell gas when I accelerate. Thanks for any help.

P.S. When I go to fuel up and I take the gas cap off. I would hear like a pressure release as soon as I take the cap off. Is that normal

 

The gas tank pressure is normal but your fuel pressure is what you should worry about. Do you have a stock fuel pressure regualtor?

 

No its an adjustable fuel pressure regulator.

 

put a used stock one back on it most of them are interchangable. if it is just a ZC with nothing done to it you dont need an aftermarket one.

 

Well I believe its advanced by 17 degress and it has a full exhaust from headers to a skunk2 full exhaust. cold air intake. adjustable fuel pressure regulator and its hooked up for 100 shot of nitrous.
