Last 5 days the error came back 3 times and all in the same situation.
Driving on the highway, normal speed around 120 / 130km.
When the error pops up, I felt some kind of power loss. I tried to drive harder, pulled down the gas, but the car had no traction.
This all happened less than a minute and the traction and power was back again.
Maybe, like I said before, malfunction of a sparkplug or something
When I erased the code everything was fine again, till the next pop up...

Keep you informed,
