Jeff, thanks for the reply. My x is a 2002 with 118000 miles. 3.3 non supercharged. v6. I did have the codes cleared. With the ignition on and without starting the engine i checked the codes again and it came up P0328 knock sensor high input BNK1. How can that be if the engine was never started after the codes were cleared? I will try a scanner with "freeze frame". Thank you for the info. James
