Hi Mike, what's the code number that's coming up with that?

Customer: replied 1 year ago.
It was code 7, thanks
Customer: replied 1 year ago.
Correction the cod is p0455 mod 7, sorry about that.
Expert:  K. Wiggins replied 1 year ago.

Thanks, ***** ***** common cause of this code are a bad O ring on the gas cap. Inspect your to make sure it isn't flattened out or torn. IF that looks good check all the evap hoses for cracks. (I'll post a diagram below)

If both those areaslook ok the next step is to perform a smoke test on the evap system. This makes it much easier to ifnd the leak.

I'm going to work on that I'll get back to you later, I'm on disability now so it may be a day or two. The last time i gassed up the cap felt like it was binding a little. I'll fix that and check the lines.

Sounds good, I'll talk to you then

Customer: replied 1 year ago.
I inspected the hoses, all looked good. I bought an aftermarket fuel cap and swapped the rubber seal, reset the battery. I've gone 150 miles with no check engine light. At 300 miles and no light I'll give you a 5 star rating and a tip. So far so good, thanks.

Glad to hear it's doing good so far, let me know how things progress.
