2005 gtp 132k miles. Got the car with a miss on cylinder two. Turns out maybe someone pulled spark plug wire out back there. I plugged it back in. It ran better , but it broke up at wot. So I changed spark plugs and wires. Acdelco. Car now has full power and not missing anymore. Drive ten miles now rattling under the hood. Sounds bad. I got the car at an auction. I'm thinking now someone pulled number two wire to mask the problem. Car is in great shape. Interior perfect. Could it be the supercharger or can I really have Rod knock at 132k?
