I just purchased my 91 LS Integra for $750 dollars. I drove the car home idleing like **** the whole time cutting off etc. I checked for a miss fire and number 3 cylinder was miss firing. I missed with the distributor and turned it forward. This eliminated the miss fire. I am smelling gas coming out of the tailpipe however. So now it will idle when I don't get on it hard but when I do get on it will sometimes cut off as soon as I get off of the gas. Any help would be great.
