I have a problem with my 96' S6 AEC handheld switch.
A Prins VSI gas system was also installed.
It has been running a somewhat undisturbed idle since then, visible at the rev indicator (swings about 50 rpm) and is easily noticeable from the inside.
Even before the installation of the gas system, noticeably better for petrol and gas operation on gas.
For about a week now he has also been outcasting and jerking

When I start driving(Kalter Motor) there is nothing to feel during the first 300 meters afterwards it starts. It jerks strongly and accelerates very jerky and takes bad gas.
In idle but again everything is in the right place.
I drive very gently and switch early when it's cold, as soon as it's self-clamped out of gas it's gone.
Then I switch to petrol mode again manually, the reckless factory starts again, no matter how warm the engine is.
If I give it full throttle, it pulls twice strong and then pulls through without jerking.
What I still noticed is that it also better pulls/has more power in gas operation.
In gas operation, I only have a slight jerking when I hit the full throttle.
I've been looking for false air, without results.
Spark plugs are new from NGK in.
I've got Lambda probes, stay the same!
Where am I supposed to go?
thank you and greet Manu
