    At a stop light after a 10 minute drive Ecu light came on. Went out about 30 seconds later. Started the car 2 hours later and got Mannitino failure. Shut car off restart no mannitino light. Then got ECU failure light and steady engine light. Car drove 1/2 hour no misses all gouges operating properly. Any thoughts?

    Age of battery? Lots of short trips? On a tender when you're not using it?

    Going to go on a more aggressive ride and get revs up. That's what was recommended

    Thanks, I've been told it happened because of a misfire. Obviously eliminated light. Going to try spirited drive with higher revs and see what happens.
