well yesterday night driving home from work my engine light comes on. doesn't turn its self off all the way home. so its on for about 25 minutes. i get home check all wires connections and all clamps to the cold air extension i recently installed both before fest and during and everything looks ok. disconnect the battery negative side and engine light went away. i know that i should of had it checked first but i have not time since i came home from fest. i feel if it comes on again today then there is a defiant problem and it will need to be addressed. the same code came up 9201. the universal code for bull sh!t. if you guys have any suggestions please let me know. thanks!
