We had the timing belt changed at approx 33,000 miles (which the dealership caught while still under warrantee). Within a few months, the car started backfiring with acceleration. By spring the issue had increased in frequency and brought it in. The dealership cleaned it out using the walnut shell process (see previous complaint) and been good ever since, but, occasionally feel like I hear an occasional little 'backfire' which I recently informed the dealership. His explanation was that I need to drive the car at a higher RPM's to BLOW the carbon out. Hopefully this will remedy the problem😬😬😬
