G’day, writing in from Down Under - (we’ve heard about the show down here)!.. Mates, I have a Toyota Yaris '07 … The car has been running pretty rough and ready over the last few weeks… During idle, it started rattling & shaking pretty hard… this progressed with the add-on feature of changing revs during an otherwise steady drive… It chose the (in)opportune time of driving with our 3 year old son, grumpy at that time, down heavily trafficked busy roadways during the holidays and stalled 3 x times… It is in the garage / service center for the 2nd time … They are stumped. They’ve checked air, fuel mix, filters, injectors, spark plugs, etc., basics. Computer diagnostics show nothing (briefly showed fault at Cylider #4 but then that changed and now showing nothing). Toyota Technical is (apparently) stumped. They are talking about needing to order a new computer from Japan (minimum $1200 just for the part).
Any thoughts or experience that I can pass on to the mechanics…?
