[QUOTE="SLefler, post: 427987, member: 19330"] I have a 2008 Rubicon with 95,000 miles. I was performing the 100,000 miles service which requires the cleaning of the Throttle body, replace the original Champion spark plugs, New spark plug wires and coil. [B]Sharing a surprising outcome:[/B] I purchase (6) Autolight 5426 double platinum spark plugs (OEM recommended replacement). I had a rough idle and this Code P302 came up from the code display on the speedometer from the ignition key (3 times) process. I replaced the P0302 code faulty Autolight spark plugs with new NGK Iridium spark plugs and the rough idle and the code disappeared.
