Ruckle and twitch - a cause!

Hello!

A few days ago, I got caught, too.
Only stutters and stumblings, DReh number fluctuations and incredible gas spills.
So I rolled the forum and diagnosed under the symptoms an increasing probability for a defective lambda.
So with a friend plug off and see if the quieter went (not the friend ;-) - but nothing there.
Hmm. Too bad, because the friend still had Lambdas from the 200 20V there, which according to Audi dealer and ETKA are supposed to be identical from year of construction '89.
Thus, while despair and perplexity were threatening to grab, the view fell on the tube, which duffles from one valve cover to the other above the air mass meter and is mounted with a kind of bayonet closure. Both ends were nearly torn down.
Despite all this, I did not attach the greatest importance to this, since it is not a turbo engine, of which I know only too well under pressure and other air problems.
First of all, temporary patched - no change, which was not surprising. I thought: Wat should it, it has to be done anyway, even if he is not the troublemaker. So the next day, ordered from Audi (approx.23,-Euro plus), built in, by the way, air filters and candles made, but they do not spew a roll for the result, and see: Everything perfect - my big one purrs again like a clockwork!
I'm completely beside myself with joy (I don't have anyone else but I could be ;-)

So, boys and girls: If you should have this problem again, why don't you look at this guy first?

Perhaps this contribution will help one or the other!

Greeting from Hamburg,
