I asked for help a little while ago and it was helful but not my solution so im asking again. VW passat 1999 not running well, symptoms are start and immediate stall unless u gas it then it gives you s chopped up response, choking, rpm between 0 and 2.5 are rough, hp loss on high and low end wont pass 4.5 rpm driving. Changed coils, air mass flow, sparks, removed catalytic, air passages are opened, turbo runs. When computer goes in default mode everthing runs, removed air mass, temp sensor, and catalytic everthing runs. I t seems to point to the ecu 8d0907557p which im having trouble to locate one. Have only found 1 at 400$ dont want to buy it if its not the problem. Any suggestions before I buy this unit.
Ty in advance
