Thx for all your answers!
A little bit from the story. I rebuild the Engine completely (New Pistons, Rods, Crankshaft...) The car ran very good for like 3-4 Days. After that i had a problem with the fuel line and my car catcht fire. Luckily i was near and had a Fire extinguisher in my car. So i could save it. After that i needed to change many things like the wire harnesses the ECM and Dircetinjection ECU. After i changed the ECM the car ran better but my CAT was glowing light orange so it was very hot. then i got the code that the car runs lean. After some searching the code was erased and i tried to drive a few meters. Then the codes for misfire came and also the P0019(Crank/Cam position correlation).
The DI ECU is grounded completely where should i look for a vacuum leak?
I hope now you have a better feeling for the Problem. Thank you for you time and help!
PS: I have a big Leak in my exhaust system right after the first CAT dose that say anything?
