Although not a big problem, I live in the nice cool UK and I have had the skip fire cut in on three occasions. Once in an hour long tailback creeping past Stonehenge. That time the engine really did not like it and really coughed and spluttered, skip fire did not seem to be enough.
My dealers suggestion; switch the engine off! Not so convenient in constant stop start.
I don't think they will be needed very often, but i would rather be able to switch them on for the short while and avoid a very hot engine.
