Thanks good tip ,the problem is that it only seems to flash when Im on a long down hill section of highway ,I can wheel all day on the Rubicon trail and it never comes on until I get to a long down hill section of highway .I will pull and clean the cluster plug though,I have checked the gauge function right after the light flashes and they check out fine , I do this by holding the odometer reset button in and at the same time turn the key to start without cranking the motor over and the computer goes through and activates each gauge at diffrent voltages ,they always pass with A done code showing on the mileage readout. It just might be haunted........ THANK YOU FOR THE INPUT.
