So are you still popping codes? If you are still misfiring I would check the spark plug wires. Also, if you still have your coils keep them. They are probably better than the replacements you got. Or better yet, put them back on and try to return the new coils. Anyway a shaking car tends to be a mechanical thing, but that contradicts the misfires. Change/check the wires and have it scanned and get back to us.
