Ok so i have something fairly common, unburnt gas coming from the exhaust at idle. My car has been sitting while i slowly am putting it back togeather, how ever i haven't driven it down the road yet. I replaced the O2 sensor, coolent temp sensor, o-rings on the injectors thinking that is what it could be from with no luck of it fixing my problem. At this point im just trying to figure out what else it could be. It will revv past 2500 so its not the MAF. Any ideas will be taken into consideration.

thanks,
chris

That's not gas. That's condensation. Having it actually shows that you are getting optimum combustion. All cars do it when sitting and warming up at idle.

Even with a bad ass rich ratio... I don't think that fuel would come out the exhaust... this is condensation ;) and it's normal
