I just bought a 2006 Mazda 6, 4dr sedan I manual. 5 days and 210 miles later the check engine lights goes on. Thankfully I bought it from a dealer know for good service. They replaced the LDP and the code is cleared,but now the rpm are running high. 65mph at 3, 70mph at 3.25. Before 2.5 rpm at 70mph. Why is it running high? BTW the dealer will be looking into it and fixing it. Are there many problems with the 2006 Mazda 6?
