When I give my car more Throttle than usual (just because I love the way it pulls
) I can smell gas right after for a short period of time. I presume that I must run rich at WOT (which I prefer than running lean). So if his car runs rich, it could smell in the car, no?
Besides, my first car which was a 1986 camaro used to always smell gas in the car. I found out that one O-ring from the manifold was loose and kept getting loose so I was tighting the screws once in a while. I ran a full summer with that car that way, that must have been bad for my brain for sure! lol
