Hey My car CEL came on while driving down the road one day. I just reached 100,000 miles on my 3.0CL. So I didn't think anything of it. Than I took it to autozone and hooked a computer up to it and got a code p1457. So I wanted to know if anyone had some experienc on the subject. And it definitely isn't the gas cap so.

 

P1457 in a Honda/Acura is a leak detected in EVAP system, it very well could be the gas cap. Have it reset, if it comes back on try swapping the gas cap, otherwise your going to need a fog test performed on the EVAP system. The only other possible cheap easy fix would be if you filled it with gas and filled it to the very top, it can flood the charchol canister, purge valve, etc... causing the CEL to be triggered, make sure not to over fill your vehicle. If you did fill the vehicle up it may take several hundred miles for it to all evaporate from where it is.
