Engine misfire

[TarMinyatur]

Took my truck to the dealer today:
codes p0301, p0302, p0303, p0304 were in the PCM indicating misfires in each of the cylinders.

Dealer told me that they could replicate the issue and it was due to water/ice in the intake. Apparently there's condensation forming into the intake. After cleaning the intake the truck is ok and doesn't misfire anymore.

They told me that it's the second Hybrid that they work on doing that and on the first, a Ford engineer provided them with this temporary solution and told them that Ford is aware of this problem and is working on a long term solution. Still, I cannot wrap my head as if it's because there's water in the intake, why the hell would it stop misfiring when engaging drive (or neutral/reverse)...

So, today everything is good but issue could rise up in the next 2 months of winter over here. No choice but to wait for Ford to release a long term solution.

On the plus side, I could have them apply the updates regarding TSB 22-2493 regarding brake grabs which I was waiting since I took delivery of the Maverick back in March 22

IIRC that was the diagnosis of a similar issue affecting gen 3 Prius's, and Toyota had an updated manifold. Mine did it a couple of times on damp mornings, and cleared up after driving to the end of the block.
Perhaps the ECM on the Mav alters the engine control enough when put in drive to make the engine less susceptible to the moisture.
