Hey guys... just wondering if anyone has experienced anything similar...
I was driving last night and my car felt as if it was running rough.. you know when it doesnt feel right. The engine was fully warm but still felt umm out of tune?
I woke up this morning and drove to work and the M was back to normal...
hmmm...

Was there sudden air temp difference?

Sometimes ECU takes some times to adjust, which is usually a common thing for MAP based system.

No not really... same similar temp.
But if I remember rightly I started the car and drove it straight away.. I didnt give time for the Idrive screen to load.
