How does the performance differ between neutral and drive? Could be something as simple as a bad plug or plug wires. I recently picked up an intermittent stumbling idle after some recent work. It idles rough in gear and smooths out in neutral. I'm thinking I have to go back over the plug change I just did, but haven't had the time.
