Blu is a 97. he does not have a pressure senssor (CA cars may) on the tank to throw a tank code. Ocassionally i would smell a heavy gas smell. Today Blu developed hesitation. At parking lots speeds it felt like someone was pulling him back then letting him go. I checked all the fuel lines and smelled a we bit at the filler neck (EEK). I noticed the cap stopped venting when filling up.

 

For 9.00 i figured what the hell and replaced the cap.

 

All issues solved. I knew a bad cap would cause a gas smell (mine would come and go so hard to track down) but did not realize it would cause runing issues. Thinking about it with the closed evap system basically the cap caused something similar to a vacum leak.

 

So just passing this on as an FYI.

Kick that trunk monkey and his whole gang off the back of the car!!

 

I know that (or it seems) subaru vacumises the tank (at least when I open the filler it always sucks air in). Could it be that there is a vacuum leak then.

No thats normal actually. Minr stopped doing that last week which i thought was odd, now i know.

 

The cap itself became the vacume leak
