Yeah it takes awhile after I clear the code, but the p0302 is the only code that comes up. Like even today I cleared all the codes and went on a 100 mile trip and every time I stop for a stoplight, it violently shakes anywhere from 5 seconds to 30, and the weird part is it will even out after that and then it idles smoothly. Then at the end of the trip, I revved it up once in the driveway, and immediately let go of the pedal, and it violently lurched for 2 seconds, then stalled out.
