stuttering at higher revs....hot weather?

[Hongkongfooi]

Some stuttering at higher revs when the air con is on ( i think only).....its done it about 4/5 times in the last week.
Anything to worry about or is it the heat coupled with aircon under full load?

I will be seeing simon hopefully within the next couple of months for a tweak to the map anyway but a bit at the moment.

i get the same when its 25c+ and i've got the air con on full whack. its just a quick hesitation, then it picks up again.

thanks steve...its a bit more than that though, and doesn't always clear.

Its a bit cooler today so will try it again later.....it still pisses past every other driver on the road though!

Any particular gear or is it under load in 4th, 5th or 6th. Mine sometime judders/misses under full boost.

Air con may inducing more load through the engine, therefore putting it into a different zone/column of the timing/fuelling maps.This column may have less timing or more fuel 'for safety'. But it is a little too safe and hence is mis-firing.

If it is that, it's quite easy to sort with a tweak.

Most likely the aircon compressor cutting in and out.
