    idle hangs sometimes.

    h/c/i 2000 ls1 camaro. 231/242 .617"/.592" 112+2
    the first time i start my car during the day it idles fine and if revved in neutral or in gear it comes back down normal. after that i can start it up and have the idle hang, then immediately kill it and restart and it idle fine. blows my mind. any ideas?

    here ya go. i noticed that after a little while of driving it starts driving like normal. just now when i scanned this. i started it after it had set a while. it ran fine. i drove a little. stopped, killed it. the idle started hanging drove further to get to a spot i could record good data,but then it had stopped. i killed it, started it again, and it did it again.
