Re: STRONG gas smell 93 civic coupe.
Ummm...gas leaking 
Is it actually a gasoline smell, or can it be an exhaust leak smell?
You really are giving much info for anyone to go off of. More details would help.

Re: ZC with EX head swap problems.
Check for vacuum leaks or a unplugged hose.
It's to much of idle for a small vacuum leak so you are looking for some line disconnected or broken.

After check for fuel leaks as the guys recommend, if you not found any I have a few in the shop with purge valve broken hoses (vent line to charcoal canister)

It's coming from my exhausts but it's strong not like a normal car.. Can it be cause I don't have a CATBACK?? The person who I got it from has some kind of after market OEM exhaust on it . does that make sence? I bought the car for 300 for a winter beater
