I noticed something about my V8.
And that is, if I tap the gas pedal slightly in the empty run, then the speed goes into the cellar, shortly before the engine dies, and then it goes up again, so it takes on delayed gas.
Just as if I wanted to go to D, like he's gonna swallow himself or something.
Also not always, but often

If I give a little more gas, he'd better take it.
The empty run is itself stable, no fluctuations.
I cleaned the LLRV today, without success, everything as before.
Could it have anything to do with the lambda probe?
He doesn't have wavelike acceleration.
Consumption is 15-16l normal driving overland.
I guess that's almost the first probe installed.
I ordered an original bosch now.
A PT bj.90 with 251tkm is on the clock.
