theDreamer may have that down. I wouldnt know tho cause mine is always warm. LOL Go out side 5-8 mins before I leave and start it up. :)

The engine code shown was the code p0300 or something similar. Random misfiring. Turns out it was the spark plugs causing the problem :/ The idle is now very smooth. But will visit my local tuner for little touch up to make sure.

The idle surging up and down is b/c your tuner must tune the MAF @ idle instead of using the fuel comp table.
What do you mean tune MAF @ idle instead of fuel comp table, I'm having the same issue but seems all the tuners are using the fuel comp table. Do u have any screen shots or examples ?
