I've gotten this CEL 4 times since I got my 06 in March.
P0457 Evaporative Emission Control System Leak Detected (gross leak)
This is also known as the gas cap code. I'm going to call Subaru and bring it in for service. Problem is I have Cobb stage 1 mapped right now. I got this code before i ever mapped to stage 1.
I'm kind of nervous about bringing it in with it still running the Cobb map. Problem with unmapping is I think I'll lose the code. Subaru told me they wont do anything unless the code is up. If i revert to stock Iím sure Iíll get the code again in three weeks or so. The last thing I want to do is get my warranty voided.
So do you think it will be ok to bring it in running the cobb map? Or should revert to stock and wait for the code to return?
