I know driving the car harder than your average grocery getter, will wear on the car faster/harder, but I am not tearing around all the time. And these problems started to show up around the break-in period..
I can accept that the allignment/brakes may have been aggrevated some spirited driving, but the last two always happen in a straight line. Even driving for two hours in heavy traffic on the highway, I get this bogging. One weird thing is I don't seem to have the hesitation I used to feel around 4000rpm. Maybe I'm just used to it, or maybe this all means something...
