Hello, after starting the engine, it actually runs clean at speed but after a few minutes, whether the automatic selector lever is on P, D or N, the engine simply goes off. We have attached an original Opel reader to read out errors. Gears selected, says the reader, no communication with the vehicle. Before this error occurred, the engine went out, we had spark plugs changed in the Opel workshop, because they were allegedly over. Weis It’s the first Omega my son bought. He doesn’t want to give it back. There’s still a lot to do but he loves the vehicle. Km 188 000, built in 1999. 2,5 l V6 (V94) Oh well, I forgot, the Fzg jumps after going out again and again immediately and sometimes it runs longer sometimes shorter before going out.
