The Pcm is detecting an Evap large leak. I have traced lines and found no faults. I was thinking maybe the IAC was at fault or the PCV valve. Not sure tho. Dont have any tools to test the system.

Wouldnt be those. Theres a valve on the tank. And then theres a vapor line running up to the charcoal canister. From there to the purge solenoid and then to the manifold.

Best thing to do is get a smoke tester to do it because altho it says large leak. It can be very tiny.

Also did you check the gas cap?
