    My idle is horrible

    I can't seem to get my car to idle correctly. '03 Cavalier - 2.2 Ecotec, Blower cams.

    Very often when I push in the clutch, the rpms will drop to ~400, then they'll fall to zero. I can keep it running with the gas pedal.

    Also: starting is a pita. I need to tap the gas to get it to start.

    I started changing the Idle VE table because it was idling lean. I changed my idle values to the Low RPM Coastdown values and smoothed it because I thought the drastic change in values may have been causing he problem.

    What can I do?

    Tune and log are attached.

    I've gone back to the stock Idle table because it was better, but the problem remains.

    Can I set up a histogram for this?

    Um...I fixed it. I realized I was kinda dumb and made a histogram to help me out.

    I had someone look at my tables, and he told me they were choppy. They weren't smooth at all because I wasn't using the smooth button when changing my ve tables. Some dumb on my part, but all is well now.
