Hey guys so I just got my car back from the mechanic after an extensive galley gasket repair. He replaced the gaskets as well as the engine timing set including chains, guides, thermostat, waterpump and all that. I got it back from the mechanic yesterday and I put about 35 miles on it since and to my surprise the car went back in limp mode along with check engine light. I have no idea what could be wrong now as I just got the gaskets replaced. Any help is appreciated. I own a 2009 g37xS sedan btw
