Just recently purchased this cx7 turbo with 100,000 miles for my daughter, had it checked by my mechanic before buying it and it was in really good condition and very well maintained. The turbo componants on the engine were replaced before auto dealer offered it for sale. The check engine light came on after driving it for 6 weeks and 1,000 miles. I Took this 2010 cx7 turbo to my mechanic and he said the code suggest a misfire. He checked spark plugs, compression, all connections, and there were no issues. He suggested having injectors serviced with BG injector cleaning service. They put it back together cleared the code and test drove the vehicle. It runs great but after I drove about 50 miles tge engine light came back on but its running great with no other symptoms. I am afraid to bring it into a mazda dealer because of cost. Does anyone know what this could be? Thanks!
