If it is shaking, it sounds like a misfire problem. With the engine idling, unplug the injectors one at a time, when you unplug one that doesnt make any difference in the way it runs, that is the one that is missing. Then pull the plug to see if it looks wet or dark, this could indicate a bad coil (if one coil per plug) or a bad wire. If plug is white, you may have a bad injector
