EVAP check engine light

[TheBigRig]

So I keep throwing an EVAP code, cant remember the numbers right now, but it seems related to going heavy or full throttle it will throw the code. Any insight on this? Where should I start looking.

Thanks

Options (without knowing the exact code)

1) New gas cap
2) Spray WD-40 on the gas cap seel and clean it really well.

Without knowing the code, it’s the most common place to start.

Thats what I figured, I tried screwing the cap on tigher than normal but to no avail. WD-40 on the seal sounds like a good trick. Ill see if I can find the paper the auto store printed out for me, its got the code on it.
