Hello, my engine wasn’t running right anymore… A little complicated! Audi Coupe Quattro, BJ 86, type 85, 100KW, KV, fan manifold,… Short of history: engine went great, no problems… vehicle was completely dismantled and restored. was finally ready again that I could make first start attempts. No modifications were made compared to the previous condition in relation to the engine, only replaced the underpressure lines, new ignition cables and everything completely cleaned… So at the first start attempts the engine ran generally very restless and smoked rather white… At low speed as if only 4 or 3 cylinders would run, at higher speed then somewhat nicer, at idle speed then died away immediately… spark plugs switched and spark checked, everything ok. My further guess was then the injection. Have again cleaned all the gasoline lines and the complete injection. Empty running controllers laid down and cleaned… Yesterday then again the next attempt was due: engine ran very bad, then super wet… So I got rid of it then ran roundly and cleaned up after 1min. Did not have a constant run again.
