Yaris Throttle over-revs changing up - Toyota Yaris Forums

thanks to those who have responded, I've done some experiments. I can get over revving with no foot on throttle (just crash out of gear and push down on clutch to go up gear. it seems to be something in the ECU that's being kicked off when it senses a gear change

I'm not talking a 200 RPM increase, we're talking 500-1,000 RPM change. 200 is what I would call normal with my other young cars with similar technology. Most of my gear changes are at low revs, there is hardly any over -revving when changing gear at 4K or above. Richie76 may have nailed it with the emmisions thing, Another of my (2 year old) cars will flood if driven < 20 feet (like taking out of garage). It was explained to me that modern cars have a much more 'sealed' fuel system recycling unburnt vapours back into injectors/carbs rather than the old enging/exhaust/athmosphere system
