I just got my car back 2 days ago from a rear ending accident in which I was hit. It's a 1996 Camaro RS 3.8L. And today the Service Engine Light comes on. The car runs the same. Perhaps, a slightly noticable rougher idle, but nothing really. So I scanned the code, and I got the P1441 code. Reading "Evap System Flow During Non-Purge Conditions". Any idea what this could be?
This is the second time I've got my car back from this shop for a collision repair, and within a day or two, my Service Engine Soon light comes on.
Any ideas what this is and how I can fix it?

 

I've been searching online and found some people say that they had similar codes when they put on a locking gas cap, which I do have. I don't know if that could be the issue?

 

I had the same light on my camaro, I changed the canister purge solenoid, that worked, later the light came back on and i replaced the fuel pressure regulator, I went to Autozone and thats the parts that their code reader said neeed replacement.......SFC
