my 2005 gxr70 has had the same indicator lights twice now. Once at 110000 miles and again at 160000. All I did was to reset the compu5ter flag that momentarily indicates a problem. After the reset the car triggered the indicators again ( 40000 miles later) another reset and all is fine. Smog tests have been simple pass. California no less. sounds like dealers were trying for expensive business.
