Ruckle 9.5Tid

Hello Saabianer Have already mentioned a problem like from others here already. I can go shopping with my 3.0 Tid (engine changed just 2 years ago). At the hinwaerts he goes like the sow and at the homewaerts after restart I almost no longer come from the place. Is alternately there and then again not. Little bit too much gas and he jerks as if only a cylinder was there.The problem has slowly crept up. At the beginning he is only on the highway on fast drive plotzlic But now almost always with just a little too much gas. Diesel filter is new.At the beginning I also poke.Air filter is also clean. Can it be the EGT? Can it be removed and cleaned? Pump? Or air quantity meter? Who can help me? Gruss Noldi
