Any chance you can add a few details or observations? Have you checked the diagnostic fault codes? Is the Check Engine light on?

C'mon, put half as much effort into this as I am. Thanks to a major house fire, I drove 20 miles round-trip to sit in my library's parking lot to see if you posted a reply. The least you can do is give me a little something to work with. Is this the description of the diagnostic fault code? I have no idea what a "sensor G" is. Do you have a number for the fault code? I can look that up and try to figure out where to start. In the meantime you should also be getting a code telling you which cylinder is misfiring. If you do, try switching the new coils between that and one other cylinder, then you can also switch the injectors between that and a different cylinder. Erase the codes, then see if a misfire code sets for one of the cylinders you switched the parts between.

Switching parts is especially helpful for a misfire you can't feel but is being picked up by the Engine Computer. If you can feel the misfire, unplug a coil or an injector, one at a time, to see which cylinder doesn't cause the engine to run even worse. If you can identify the cylinder that way, consider performing a compression test, and check for a rocker arm that isn't moving much due to a worn camshaft lobe.
