    Runs fine, Rough idle and stall at start up, every start up

    Somewhat, I've for through and changed all the sensors, it always will start, I just have to help it idle for a couple minutes and then everything is fine. It's definitely running rich especially at start up. Rebuilding and cleaning the tbi is the next project

    Runs fine, Rough idle and stall at start up, every start up

    I personally haven't done a tune up on it. I've had the truck for about 6 months and it's always ran fine. I will do a tune up and report back

    I like to think I'm pretty good about not touching touching the clutch unless I'm shifting. But considering my truck is currently in a parking lot and doesn't move in any gear I'm pretty sure it was the clutch going out. Yay

    Nv3500 to nv4500 swap

    It doesn't rev high on its own unless I'm trying to go up a hill but it's all pedal related. But to go from 2nd to 3rd I have to-- Clutch in, shift to neutral, clutch out Clutch in shift into 3rd. To go from 4th to 3rd- clutch in shift to neutral get the rpms over 2500ish and it'll slip in...

    I will give all of those a try, the only reason I was thinking NV4500 is if you take off in "1st" you can redline and go about 8 mph. The original shift knob wasn't on when I bought the truck. Clutch seems good, the tranny does have some issues tho. I'm thinking synchros tho
