I wouldn’t bother with the injector cleaner, that’s a real stab in the dark. It’s obviously an intermittent problem that doesn’t occur when it’s at the dealership, or show up on the diagnostic checks. Next time the engine malfunction light comes on take it straight to the mechanic and have it checked, if you wait for it to go off there is little chance of finding the problem.

THE jury is out on the Viva. It simply hasn't been around long enough to enable a judgment.
