runs rough at 1600rpm

My truck hits a rough spot at exactly 1600 rpms. Goes away higher and lower. Any ideas?


Thanks

Pull the spark plugs and take a look, that may help lead to a diagnosis. If the plugs are not so new, then put some new champion coppers in it and drive it some and once it cools down take another look. For example, if two corresponding cylinders that share a coil are looking worse than the rest, then change that coil pack out.
