    So since I had sucked in a lot of water on my last outing :rolleyes: (http://coloradok5.com/forums/showthread.php?t=170044), my truck has been pretty stumbly and not up to its full potential. But today, it seemed to run better until I made it do some highway duty for about 15mins at 3200rpm. When I got off the highway it idled higher than usual, like 1100rpm. When I got home I lowered the idle but then it came back up again. I then tweaked the idle mixture screws to a better possition then readjusted idle but it then came back up. All I can say it WTF?

    Oh and its a Holley 600cfm 4160.
    In about a week I am going to replace the intake manifold and rebuild the carb, but in the mean time, WTF?

    the hairline crack probably got worse or the cold water splashing might've added another one. other than that... I dunno.

    So today the truck idled real low, I guess couse it came down from yesterday. So I raised the idle so it runs fine now.

    But what the hell was that all about?
