I cant tell where its coming from, but i definitely get a bad gas/exhaust smell coming in with the ac on. Anyone here have this problem? Help...

 

ttt. This is under normal driving, not boosting.

 

do you still get it with the Recirculation button on?

sounds like you have an exhaust leak. park, engine running, pop the hood, put your face above intake manifold and get a good whiff.

 

dont get the smell with recirculation. Ive tried smelling around different areas of the engine bay with the car on, but i havent been able to pick up the smell. Ill try checking around the intake mani.

would a bad catalytic converter cause a stench to come up through the AC?

 

check to see if your fmu is leaking fuel if you are running one and if you do have one and it is leaking it is on the top of the firewall and the gas fumes go right into the vents there

 

yeah, if u had an exhaust leak you'de be able to smell it.

retighten your fmu connections. I had them come loose on me and the fmu was spraying fuel all over the place when I boosted.

 

and most likely you put an extra peice of fuel line in there mine bursted due to the presure and heat in that area

 

had a slight smell coming from the fmu, so i tightened all the lines. I definitely had a fuel leak from the line on the second fuel pump, fixed that. I still have a smell coming in. So the search continues

 

check all of your fuel conections like on the rail on the filter and on the fpr but then rember the smell might be there for a little bit after you have it all taken care of
