Engine problems Omega A C24NE

Hello! Since this morning I have the following problem. After the first start the car ran as usual. On further drive I noticed that the car took a bad gas. At first I thought of moisture (was here the days awfully poured) and a few times the gas pedal penetrated strongly. When the engine was really warm it then actually ran round. After the parking of the car and later again he wanted to do it again not so correctly and eated around again and took even ke in gas. Turned up a couple of times and at some point it ran round. Now it always starts badly and can not be convinced any more. In addition, it also has misignitions. Recently all ignition cables incl. coil came new to distributors. In addition, I cleaned the throttle flap and the engine ventilation. I also put another idle switch in there once, but does not change anything. Does anyone have an idea here? Greetings, Martin
