What is your question?
Any idea root cause of this phenomena on a 180,000 engine? Spark plugs replaced, Fuel system tuned up recently, replaced Fuel pressure regulator and still erratic.
which leads to my next question-Is an Audi dealer the best place to bring this type of problem? I prefer another trusted mechanic, but, when I mentioned the type of problem I was having he seemed puzzled...
