Didyou ever figure out this "valve duty cycle" code? My truck just threw this code this week and I 'm running low on warranty miles. Only about 6k left...

MIne does the same thing... idles down VERY low and stalls at stoplights.

My throttle positioning sensor is new and I'm not getting any codes either.

Is it the actuator on the throttle body that goes bad?
