Yes, it is after I turn after downshifting usually from fith gear then 4th, 3rd, .and am in second gear. After the turn I hit the gas and a couple of hesitations and the misfiring. I am researching how an EGR valve functions. I think if the valve is stuck open it will cause misfiring. I am not an auto mechanic, I work on things that go into space. This car has gotten me interested in working on them.
