Hi Mike and Amanda.
Its a real shame that you are having issues with the Cruiser. Its the one thing that you really can't afford to have problems with without suffering major heartaches!!!
I don't know if you've had any time to read any of the
forum stuff on your travels, but I recently posted and issue on behalf of my mate. His 200 wouldn't change above 4th Gear although it wasn't cutting out like yours. None of the mechanics could resolve the issue and it was duly booked into Toyota
Karratha (he lives in
Tom Price) where they also were pretty clueless just listening to the symptoms. Fortunately for Benno his in-laws were up visiting from down south. His father-in-law being a farmer by the way. Once he heard about the probs with the Cruiser he said to Benno that they should have a look themselves and get back to basics. Short of the story is that his FIL first went to the fuel filter and it was full of physical
debris. They changed the fuel filter and hey presto...........she was cured. Sweet as a nut.
I know that yours is a petrol version and the fuel in essence is more refined than diesel, but I'd like to think that there is the heart of your problem. As you, they had no warning lights, and nothing showing on the computers at the mechanics. I hope that this does help a little and that you get to enjoy the rest of your trip, which I've been following with great interest.
We are planning a month long trip to
Lake Argyle and
Broome ourselves for next year, so this leg of your journey is of particular interest to us.
Wishing you and the family good luck
Phill
