    I have had a small misfire for a while now. Today I was checking spark plugs and noticed a couple bad wires. After replacing all the wires the miss seems to have cleared up. However, for some reason the truck won’t idle anymore. I took it for a drive and it ran great, just won’t idle.
    Any ideas?

    Bad idle can often be a vacuum leak. You could have created one when replacing the wires. I would check for that.
