[98hoe]

Gas cap looks fine and I didn't hear any leak in any vacuum lines. I don't even know where the evap can is to check cracked lines. If any of you have had this problem or know where to look please help. Thanks in advance Patrick

did you happen to fill up your gas tank with the engine running? when i was a mechanic it was one of the the most common reasons people had a check engine light come on.

Don't think so. I know I didn't do it today and today is when the light came on.

Mine came on a while back same thing - and went away on its own - i didn't replace the cap it seems ok.. not sure but the light did go away on its own - might just need to tighten the cap down a little more.. ?

my dads s-10 is always throwing the gas cap code, put a new cap on it and no problems. may just not have it tight enough.

my cap is going on 10yrs old.. so it probably is just the cap itself.. - but i also kinked the evap line going to the gas tank thought i might have put a small hole in it, but since the light turned off i'm not going to drop the tank to look at something that may be perfectly fine (i un-kinked it right away and was like NOO.. - the main reason i don't like droppin the tank myself - the 2nd time i dropped my tank i forgot all about the pressure sensor in the back of the tank (98-on, 97down doesn't have to worry about this) and when the tank went down the pressure sensor snapped - i put it back in with super-glue this worked for 2 yrs last time i dropped the tank i replaced it $43.99)
