Hello, have a Corsa B with C20XE. The engine ran quite normal, every now and then the MKL went on, but after a short gas foot went off again, the cold motor sometimes did not pull right or with a slight jerk. Yesterday the Lambda went on in the city,there is bad with gas foot. Then turned it off and this morning when the MKL lighted up again. Bust to a traffic light and wanted to turn right, the coupling to switch,there the speed went completely down and the motor went off. Stupid looks there no ser The next traffic light was nothing more. After about 8min drive the MKL went out again. The expressway was then given to 80…normal gas and drove there,suddenly he no longer accepts gas, but engine is running,car is slowing down. Kuppkung stepped and given gas in the empty run,there he takes gas.5th walk inside but nothing started with gas,that’s why he switched to the 4th. Then he took gas again,but he jerked violently w As soon as he stopped occasionally, after a few seconds he did not take any more gas. Therefore he switched to the 5th again, the same game as in the 4th course until no gas took up again. that went then until the exit to the ampel. Traffic light started,after that everything was normal because motor had normal temperature. What can it be now? I ordered a new temperature generator for the STG because someone gave me the tip because of jerking with cold motor. But the with the no gas-acceptance was today quite n eu. Ask for help Jason
