Check Engine light and VSC magically came on one night. I checked and made sure the gas cap was sealed tight. The light disappeared after about a week. NOTHING WRONG
check engine light came on around 100K miles and OBD2 indicates it is related to evap charcoal canister. At 126K miles still no solution. Car runs perfect. Learned to live with CEL on :(
