16 FiST with 11k miles I just got my accessport and installed a 93 tune. The next morning on the way to work check engine light. Checked it and p0454 cleared the code and it was fine for about a week then it popped again. I have been searching and know that it is evap but not sure exactly what it might be. I can go to the dealer but it is an hour drive and they had the car for a week for the blend door. Just trying to see if there is anything I can check before I take it in.
In my searching I have found some with codes similar like p0456. Same issues? When I first got the car I made the mistake of topping off. I have never had the stalling problems that I have read about.
Don't think it has anything to do with tune. I believe it's coincidence.
TIA for any tips
