I have a 92 Audi V8, ABH 4,2l.
Wellenartige Beschleunigung/ Pulsating accleration, watch video.

ps: New Bosch Lambdasonde,plug cables- under a year old.

the video don't start......

Look at that: http://smg.photobucket.com/albums/v700/ultimateVW/?action=view¤t=MOV01433.flv
But for me, it looks quite normal. When my lambda was gone, the pointer jumped more.
Interessting would be the actual petrol consumption. Is it steady or +/- 0.5l?

Jürgen, um 5 Uhr morgens stöberst Du hier schon rum? Und dann, wenn die Sonne aufgeht, 12 Stunden Lebensmittel lieben.
Wenn's der Wirtschaft wieder besser geht, weiss ich wo's her kommt

realy, does your V8 have a wavelike/pulsating acceleration still after changing lambdasonde?

I think the fuel consumption is high, 1,6litres per 10km.
AND then i only drived highway,80-90 km/h..

Change the Lambda or first pull out the Plug from the Lambda (under the ignition distributor left), to check if it's realy the LambdaSensor or not

Michael.....da ich ja jeden Tag um 5 aufstehe stöbere ich gerne so früh hier rum

Wie war das ???? Der frühe Vogel fängt den Wurm

i have tried before to change lambda. then with a used one, now with a brand new.

No fault codes now. I have changed lambda some months ago, before that i got a fault code for the lambda.
After changed, no fault codes.

Ps: before it was much engine problems.
But the wavelike acceleration is still there..

well... do you used an Sensor with GroundWire?
Sometimes is the Exhaust not realy good grounded (Flammringe) so you need this GroundWire (brown) for a better function.. normaly you get an Sensor with 3 Wires, one white for Signal, zwo black for Sensorheater, NO Ground
