It's amazing what a quarter turn can do. I've experienced the difference in both start-up and in acceleration from standstill. The thing that baffles me is I started down this path in experiencing sudden lack of power during starting from a light or when pressing the gas hard on a turn or braking hard on a turn (stalls). While I haven't experienced the same level of issues since the 1/4 turn exercise, I still need to artfully apply the throttle to get power as needed - can't just press the pedal down hard. Is this normal? Needless to say the symptoms are intermittent. I've cleaned out the choke plate, have clean air filter in place and adjusted the aforementioned 1/4 turn. Anyone have other ideas of what may be going on? Of particular concern is the tendency to stall during hard braking on a turn. Just for reference, the car has 207K miles and had the engine rebuilt around 150K.
