Message: It's flashing on and off regularly? Mine was doing that, it was caused by multiple misfires. You might want to check your plugs/wires to make sure they are ok. The plug tips should be light grey, indicating correct heat range. If you notice glazing, or gap-bridging, it might be time for new plugs! Also check their gap. If these two check out, check the cap/rotor for scoring/cracks...
