Omega B Facelift jerks Hefty

Hello people, after I have successfully mounted the Autom. Innspiegel, there is now a new problem. The Omi ( BJ 2000/ V94 2.2 l., 16V) jerks what holds the stuff, at least as soon as the gas pedal is kicked. The acceleration is almost zero with normal gas, only with full gas it pulls clean through without a mute and twitches. In addition, it jumps badly and goes out almost afterwards. The idle speed is close to 500. . Also a candle change with contact spray and the like has not fluctuated. After reading the error code, the vehicle is technically i.o. The ignition module is at least not defective. Would you have a tip for me, what that could be?.
