Ignition oscillation at the Lacetti / Mkl

Hello car friends, I have the following problem and I can’t really make a rhyme up. My Lacetti, which I took over in Nov/2010, has been bitching for some time. A few months ago I was already in the situation that the car started to stutter at night while giving gas and lighted up the engine control light in my face somewhere in Wallachia. At that time I called the ADAC to get him to tow me, because I didn’t know exactly how to handle it. I don’t know about that. At the end of the song was a nine-hour odysse with further transport and great fatigue… The car was in the workshop a week later, with the order that it should find out something wrong with the car. Result: candles, ignition distributor, injection is supposedly not. But there was an update for the engine control that was recorded… So wurds told me, understand kan. At that time I was definitely glad that I got away at least cheaply… So much for the background… Now I’m in the situation that I have another ignition drop and started the MKL again on the weekend Had 300km before me again, but this time I drove on. At the moment the check-out is extinguished again. What I can observe during the ride and also now is that I have to give very careful gas so that the engine does not go on. More than using the accelerator pedal with the little toe is virtually not in there without stuttering, which is a little bit of a concern to me. If I step on the gas in idle, then it doesn’t stutter! Is that normal? Can you give me some advice? What could that be? You leave quite a lot to MKL with Lacetti and the bottom line are all expensive repairs, where I have to think hard about whether I still want to invest so much money in the car… the noticed that the car uses for its conditions subjectively significantly more fuel than before the last workshop stay. 10-12L instead of 9L on 100km greeting, Stefan
