Evap leak
After installing my Greddy exhaust on my 03 Z, i got a check engine light. I had a friend run a diagnostic and he said the code said "Evap Leak". I checked out the fittings and they seem tight. He cleared it and it was fine for a week then i got the same check engine light and it was the same evap leak code. I did this about three times and now i just drive it around with the stupid light on. Does anyone know what might cause this and how to fix the problem? I would appreciate any advice you all can give me. Thanks!

Also be sure that you are not melting the hoses with the exhaust
After a long trip you may have enough heat back there that you burned a hole in one of the hoses...
This will cause the evap to flip after a long use.
Just a thought.
Let us know what it was

yeah i checked the hoses a few times and there doesnt seem to be any hole or burns. I also checked the two electrical connectors and i even siliconed one of em on after replacing the O-ring. I thought this might be the problem. The same check engine light came on a few days later. I havent replaced my gas hose yet on the recall. I wonder if that might have something to do with it. I've had the car for about four years with no evap problems and after that greddy exhaust install, i keep getting the evap leak code. I figure it has to be the exhaust.

when i moved my evap canister, even after i had the hoses on tight, i ziptied the edges, and covered them in black electrical tape to keep as sealed as possible. its been 8 months, and its worked great for me. even passed emissions. great success!

Yeah for some reason, this seems to be a common issue with moving the EVAP canister for the Greddy systems. It's no big deal really, just reset the codes and move on. I have yet to find a way to keep the issue from reappearing, even after making sure all the connections are super tight.

ok thanks. i'll try to zip tie the edges. I have a recall on my gas tank hose. i havent had it done yet. i wonder if this has something to do with the evap leak? Is there anyone else who has this problem with a fix/solution. I've had the code cleared three times and yeah it keeps coming back to haunt me. what a bummer.
