Cutoff at low RPM during gentle acceleration - Yaris Verso 1.3 VVTi

I think it is simply a coincidence that your symptoms stopped after adding oil. I suspect they will reappear. Low oil level should make no difference, it is the oil pressure that matters. Now if the oil level was EXTREMELY low, it is possible that the engine would lose oil pressure. But at that point a faulty VVTi would be the least of your problems.

If the problem reappears I will update this thread. Currently the engine makes absolutely no hesitations, like before the oil change in November.

Some important point that will be useful for other users in future: If you have a problem that shows itself only after the cold engine warning light turns off, it is very likely that it is related to VVTi.
