I've had a recurring CEL for about a month now. Its been a large emission leak. I've checked damn near every vacuum line that car has and everything looks/feels connected. And yes I've checked and made sure my gas cap is securely tightened

Changed my spark plugs and in the higher RPM's my car made a ticking sound. It was gone today but today there's also a CEL. Had it checked and as I guessed it was a large emissions leak. The car itself runs fine but I'd like to find and actually cure this annoying CEL once and for all.

I'm 95% certain its not with the vacuum lines. I would be stunned if it was. Considering an exhaust leak (my car sounds a touch louder but it could all be in my head). Any other ideas please?

What was the code, P0456? It could be the gas cap, $10 fix.

Of course I didn't check the code took it to Autozone and had the code read for free. Told the lady to clear it as soon as I heard what it was.

P0455 EVAP system leak detected (large leak) ON 2 EVAP system is the code for large leak. 99% a new gas cap fixes this, you cannot tell if the old cap is defective. If your still under the basic warranty you can get a new cap from the dealer. If not look for Stant part #10838.

Thanks man. If it comes on again I'll write down the code and get a new gas cap.
