    A faulty gas cap can throw a code. I'm not sure what kind of code it would throw though.

    ok so i just picked up a bottle of gunk maf cleaner, just took it off and im going to give it a spray.....


    I also stuck my head in the engine with the engine cover off and lising for a leak and i could not hear one... but What do I know....

    I checked the connections on the purge valve and of the blue tubes beside it. I made sure my airbox and such was tight to the throttle body and Im going to tighten my throttle body as well *i had that off last year to clean up all the carbon that gave me a rough idle*

    What I know so far
    -I dont have a rough idle
    -never had problems starting on emtpy or full
    - the gas mileage seems to be ok ( im going to document it now)
    -Im also making a car log of how many times I stop and start - warm/cold and how many times I crack the gas cap....

    what a pain in the ass

    Since purge valve was replaced and still same issue it sounds like an oxygen sensor. I'm sure Jimmy will tell you the same thing.

    I wish i could take it to Jimmy but Im a few provinces away



    It was a nice day today, I took my cover off and stuck my head in the engine bay and I could not see/hear a air leak. I used a tiny wd 40 bottle and sprayed around the intake and various pipes seeing if the engine would bog down or see stuff get sucked in... nothing

    I cleaned the MAF with the right cleaner - it was pretty clean I also re-cleaned throttle body (it was getting dirty after only 15,000km)
    I also checked the gasket on the throttle body but i could not see anything...

    what a pain in the ass ill feel better once i put another few tanks of gas in the car and dont get that code...

    on a side note the 2 screws that hold the MAF in place one of them just spins and does not seem to make a great seal. the other one is nice and snug....
    Can I use a slightly larger screw, they look like wood screws to begin with ....

    sounds like you found your problem
    you can try to use a bigger screw, but if it were me, I'd just fill the screw hole with glue, let dry, then put the screw back in
