It does it when its not cold out. I think the main problem here is the PCV valve going into the Intake manifold. There is a thread discussing this problem. I think it is the one about a catch can install.
This would explain alot.
Fuel shooting out of the tailpipe???? Thats a stretch ain't it??![]()
Not really. Just not on a catted, OBD, and fuel injected vehicle. My motorcycle used to shoot flames out the pipe at high RPMs when I closed the throttle. I plugged the Air bypass so there wouldn't be any o2 to burn, so now it just shoots raw gas out the exhaust. Quite noticeable by the smell if you are riding behind me, even at speeds over 80mph. Never actually had any smoke associated with it though.
There were no cats on motorcycles 10 years ago, to burn off excess gas and improve emissions there was a hose that ran from the airbox to the exhaust system (the more you know...)
