My car idles like do-do now.
Since I put the revised cal in - when Chem2 was released - the idle quality really fell off.
As far as idle is concerned, it is just blueberry scaled to +40's. I have touched nothing else with any effect on the idle.
It's typical TD idle - smooth for a second, then A/F goes lean, miss-miss, A/F bounces back - smooth - repeat. It's just more pronounced now.
What can I tweak to try to get it to idle smoother?
