Well remember the old adage. "NEW" doesn't mean "GOOD. Here's what I would do to help eliminate some of that. Yes, it's one of those "old wives tales" to some of these damned experts around here, but IT WORKS. Wait till it's good and DARK THIRTY outside. Bust it off and let it warm up. Chock BOTH rear wheels. HARD. Get someone in the car to heavily set the parking brake and PLANT the brake pedal. Now you get under the hood, while THEY run the RPM up IN DRIVE. If you have some secondary ignition leakage, you'll know it right quick like. I would eliminate that first, because it's so easy to do and costs nothing.....well.....as long as you're careful. LOL
