Smarter people, is vapor lock a possibility here?

OP - Open up the tank cover, rock it back and forth. Take a cone put it over the opening, take a deep breath in (away from the cone), and exhale hard into the cone.

I know this has been more than a week but I think this could be caused by flooding the evap canister during a gas fill up over flow. Heard Robot mention this exactly in a video he done.

^^^ this. Disconnect the suction line for the evap system at the intake manifold and cap it off and see if that helps. Also check the state of the manifold with a small mirror all the way around for cracks while you are there.

Following! My 2009 250ie just started doing the same exact thing today. I put new injector in, checked spark plug, compression, voltage is showing 13.5VDC.

I am a bit bewildered as to what the problem is.
