P044

I had this code erased and it came again. It says something about evaporation pressure. Now in the first start of the day, it stars, then stalls. Maybe ther are conected?
Anyone with this issues?

Is that supposed to say P0440? Could be a handful of things- it's an evap leak.

Check the gas cap, make sure it's tight. Drive 50 miles. Come back and report.

Its well closed. Ill check it again just in case.
Any other thoughts? If it is the cap, should the check light go away?

it'll go away usually within 50-100 miles if it is the gas cap. may be loose but it also may be no good. If that doesnt do it the evap system will need to be smoke-tested

Most common fix on that code is the charcoal canister. I would first check the hoses that lead into that.
