    VK Wagon on Rodeo chassis
    Hi - newbie here, both to Commodores and this forum. No idea if this is the right area to post in... fingers crossed.

    I bought a VK Commodore recently, with a fairly tired looking 202. It was missing a bit, but ran really well under power, was a lot of fun to drive. Today, when I stopped at lights, it stalled when I tried to move off. It started OK, but wouldn't even develop enough power to move the car. Anything more than idling was pretty much a no go. Eventually I managed to get the revs up, and bounced it across the intersection, and it ran a tiny bit better; well enough to limp to the panel shop I was taking it to (about 1km further). Now I can sort of move it, but only by getting the revs up high and dropping the clutch.

    More info:
    - 1986 VK Commodore
    - Rodeo 4wd chassis
    - Stock 202, no smoke, oil leaks everywhere
    - 4 speed manual
    - Off the road for 10 years before I bought it
    - Drove fine for a few days

    Any hints? The car is at the paint and panel place now, so I can't fiddle with it, but they'll be annoyed if they can't move it easily, so I might have to go back and see what I can do, or even take it away again. I don't want to do that, I want it tidied up!

    Dirty filters and plugs are another easy check.
    Also check timing and spark colour while your there.
    Is the 202 carb or injected?
    Carby could do with a tune also.

    Change the ignition module before you bother trying anything else.

    Depending on the dizzy fitted....If it's the original black motor dizzy, the module will be located at the back of the block bolted to the head....If's the blue motor dizzy, the module will be located at the side of the dizzy.

    So really we need to know from the OP, whether it's injected and if it has a square piece hanging off the side of the dizzy, with 2 wires coming from it.

    That being said, I do agree with you as it being the cause

    check timing, 6's sometimes like to turn the dizzy themselves, also make sure the balancer hasnt turned as you will get a false reading on the timing mark
