Recurring EVAP codes. TSB?

[Volatile]

So a couple days after I bought my car she threw a code of P0457, which is normally check gas cap apparently because a day after it came on my check gas cap light came on.. My cap is tight, and my friend cleared the code for me. I bought an X3 SCT a couple of days ago as the same lights came back on, and now I'm getting P0455 and P0457.

I read this on the TSB list:

03-20-03 DRIVEABILITY - MALFUNCTION INDICATOR LAMP (MIL) ILLUMINATED WITH DTC'S P0442, P0455, P0456, P0457, P1442 OR CHECK FUEL CAP LAMP ILLUMINATED WITH DTC P0457

So is this a fairly common problem? Should I go to a Ford dealer with this issue? The car doesn't run any different..just annoying.

Thanks.

Might want to try swapping out the gas cap first.

I just started getting the cap light as well.... Usually means there's a leak somewhere...

I can't figure it out either!!!
