I’m new here in the forum. I have an Omega B Built 99, 2.2l 16 V Y22XE automatic. I had it converted to autogas in January. After some time he started to stutter–> LMM in the morning, fix problems ! Then he always left me at the traffic light in the petrol and gas range. Throttle valve unit blown (previous cleaning had done nothing!) – now he doesn’t go out at the traffic light in the gasoline range anymore. On gas however already! The BC also shows automatic transmission check again and again. Now it almost goes out in the morning, if I don’t let it warm up to P for 1 min. Could that be the Temp. sensor ? The bigger problem is that it is very bad in the range of 80 – 110 km/h, partly not at all or only with total kickdown accelerated. Also it does not switch so correctly. Therefore my question: Is there an extra control unit for the automatic for my model ? If yes, where sits e s; who can read it out? Is it possible with the tech device? Can it only Opel, because the other, free workshops forbid it to dive deeper into the electronics? Oh yes: the cracker was leaking and pulled air–> plan and reattached with new, better bolts and seals. So it runs now when it is warm up to approx. 80 km/h very well, but after that it swallows lightly and the transmission works somehow differently. Also the top speed is now only noc h at approx. 170 km/h. Can all this have to do with the camshaft sensor? I BREAK THROUGH ASSISTANCE !!!!!
