Why does my car drive smoother with the AC on?
I've noticed that when my AC is on there is much less cam surging and bucking at low rpms. When it's off, the cam surging and bucking will take over if I'm cruising city streets and the RPMs fall and get close to 1500 or below. What does the AC being on have to do with driveability? And what causes the bucking and clunking sound from cam surge? I'm sure those parts are worn by now.
