Will diesel cause the AOS/MAF to fail?

[78F350]

I can see the possibility of diesel contamination effecting the AOS, but can't quite connect it to a MAF failure.
Outside air comes in the intake and past the MAF and throttle body before any fuel is introduced. I wouldn't count the MAF as bad anyway until the other issues have been cleared up and DTCs reset

note: The author has very little actual knowledge of how these things interact and is much better at taking things apart than putting them back together.

Agreed. Can't see how the MAF would have any clue.

Not really seeing how the AOS does either, but not ruling it out totally.

Seeing as it was their gaffe, you can't say definitively that diesel contamination would not compromise the AOS, so I'd have that replaced as part of the claim. My $.02

??? I thought diesel pumps were the same size as the old regular leaded pumps, which are too large to fit into an unleaded fuel tank. Thought this was a federal regulation.

OP didn't put the diesel nozzle into the filler, the gas station put Diesel Fuel into the Premium tank.

If it were me, I'd suspect that it ruined my cylinder walls, IMS, and crank bearings requiring a full replacement with at least a new 3.4L engine. :dance:
