1998 Mazda Protege with 1.8L, Manual Tranny. Car has thrown a PO455 code for a month or two now (Large EVAP Leak). I had a broken EGR tube and replaced that but apparently it was unrelated.

Anything common to look for on these cars as far as leaks? Gas cap looks fine. I don't even know where the charcoal canister is on these cars. If anyone can help me out it would be very much appreciated. Thanks.

did you erase the code when you changed that hose?

 

Yea I did, multiple times. In hindsight the EGR has nothing to do with the EVAP system so I'm not sure why I thought it was related. I did a visual test and everything looked ok (nothing obviously cracked)....Im gonna test the purge solenoid on the firewall and see if maybe it is stuck open. If it was actually a large leak in the line somewhere I figure I would have smelled it by now...but if the solenoid is stuck open it would just be leaking into the manifold. We shall see.

Could be a bad fuel cap?
That's one of the most common, easiest to fix problem w/the evap system in modern cars.
