Got a check engine light about a month ago. Took it to a garage and the guy tightened my gas cap. Erased the code and it was good for about 3 days. I didn't get gas in that time frame.
Got gas then and the next day light was back. Went and got a new gas lid and tightened and went to Advanced and they let me use the computer thing and I erased the code. I think the code was P0455 (or something similar)
It was good for a day now it's back on. It says "large leak" under the code. Called garage and he said wait till weather warms up. Car feels ok driving it. No issues.
any ideas on what else this is or what I can do??

if i remember correctly. thats a evap code!

large evap leaks could be a lot of things. check basically everything in the evap system and try to find what could be causing the leak. all the hoses, the canister, filler neck, everything. if you can't see it then pay a shop to smoke test it.
have the code deleted! thats all i did.

Smoke test sounds expensive.
How do you delete the code? I'm looking to fix the cheapest way but don't want to mess anything up.

smoke test is not expensive. use to work at grapevine automotive and did it all the time on my isuzu truck (96 carburated POS) it had a billion leaks and everytime i fixed one 3 more would come up. anyways they just plug a smoke machine which uses liquid smoke (samething they use on electric model trains) and force it through the evap system. smoke comes out of the hole/leak then you can find it. easy as pie.
easiest way to erase a code if you can't get your hands on a scan tool: disconnect the battery. if you keep clearing the code and it keeps coming back then you can either just deal with it, GET IT FIXED or put something over the light so you can't see it. since you've already had the code cleared once and it came back, i don't think it's going to stop after deleting the code this time. sometimes leaks are just loose gas caps or something dumb, other times they're actually leaks and no matter how many times you clear the code it will return until the problem is fixed.
