My truck is jerking when it hits 55 mph I just had the E.G.R Valve replaced and the engine light still comes on. And we were told that it needed a Catalytic Convertor. But why is it jerking? My mechanic said that it shouldn't jerk anymore. So what could be the reasons for the jerking and the Service engine light to come?
