Can’t you do the old propane test to see if you have a intake leak ?

If it's under warranty don't mess with it. Take it to the dealer.

When you hear it idle up can you detect any change in the sound of the idle? When EITMS drops the rear cylinder the idle sound noticeably changes.

A head scratcher, because the symptoms sound identical to how EITMS works.
