well ive never experienced anything like this before. my drivers side tail pipe was wet and i assumed it was water. and the passenger side is dry and today i drove my car around and it was backfiring almost constantly! so now i think that wetness is literally gasoline on the inner-end of my chrome tips... i already knew my car was runing rich but this is the first time this has ever happened. how do i fix this? my car since ive had it (4 years) has never had the 02 sensors changed and i'm about to change my TPS as well....
