No, nothing else was changed. Maybe weather?

No, it could be rather difficult because I don't have catalytic converters now.

It is strange to me too. I did reflash ECU with GTM ROM and went for a short ride.

There is log from this ride: https://drive.google.com/file/d/0B-5...it?usp=sharing

At the beginning the issue occurs 2 times, later engine speed falls too but not to 500 rpm because speed is higher. From 1:18 to 1:40 this issue occurs several times at speed about 15 km/h.

Thanks, Robert
