Themenstarter Hello friends,I have bought an audi 80 type 89. he has installed the engine with key letters pp. I have the problem with the car that he very often simply runs out at the decoupling. when starting or in normal empty run there are no abnormalities. I have for maintenance reasons ignition cables, ignition plugs, distribution cap, distributor fingers, sealing flange of the injection system, and the air filter made new. I have in empty run everything on vacuum hoses, also from the brake force rker sprayed with brake cleaner. it did not show any effect. did you perhaps have an idea to get the error on the loop,or a test method for the leak control? the search function I have already used, unfortunately did not help me. the injection system and the flaps are cleaned. do you have to learn the flaps with this motor maybe also new? know this for example from the polo 6n,golf etc. have unfortunately zero experiences with the pp motor. look forward to your bet Räge. Greetings
