My truck, after giving it a basic tune up of plugs and cap and all that, was running a little unstable at idle or low speed. If I let it idle, doing nothing, and its warm, it will act as if its hunting for the right idle speed every now and then. I was doing some dragging of stuff around the other day with it and it became most annoying because the speed wouldn't stay put. It seemed to start after I ran a bottle of injector cleaner through the tank, but it escapes me why that would have an effect. Someone suggested MAF, but this has a MAP system, and I don't know where to start with that. FI is one of my weak points, so a little guidance would be appreciated.
