I recently bought my audi a6 wagon and did a motor swape b/c the other enginge blew. So I put one in with 68,000 miles. Before I bought the car it sat for 3 months. I put new gas in and it ran better. But now I drive it has random missfires.I changed. Spark plugs & wires, o rings, coil pack, intake gasket, cleaned out the intake completly And know it missfires when you go up a hill and coast down the other side and start to give it gas again it starts to miss. Please help!
have the same problem?
