Temperatures are slowly dropping here and I noticing that when it's 10C (50F) or less, the cold idle is not so smooth.
In the first few seconds after start up I can ear a few misses or pops and once the idles drops to the normal speed it 'bounces' around between two speeds not too far apart.
As soon as I hit the gas or get going, all is back to normal with a smooth idle.
-I get no codes associated with misfires.
-I also checked and cleaned the MAF sensor recently.
Any ideas ?
