    Has anyone had a similar situation? We have 2003 Pete 6NZ and the engine & oil light turn on every so often. They blink simultaneously for a few seconds and then they go off, then they begin blinking again about an hour later for a few seconds, and go off again. Gauges all read good and performance does not appear to be an issue. Any insight you could offer would be truly appreciated. Thanks

    Had same issue once. went to wire harness, and all other connections, pulled apart, checked for corrosion, and water. Then
    re-connected with electrical grease. Problem never came back. Also, when oil is starting to break down, light will start to blink
    when coming to a stop, after a long run. Mike-Z
