The truck recently started acting up in the last 2 days. Yesterday morning when I started it, it idled rough, and not as high as it usually does, maybe around 900 when its usually in the 1400 range for a cold start and 70 degrees ambient. Then as I am driving, coming to a stop sign or a light, when I push the clutch in, the rpms drop much quicker than usual, and the truck dies, or fights back from 200 rpm and idles low at about 400 rpm. It also seemed like having the brakes on while decelerating may have had an effect.
I know there is something that cuts fuel when off throttle, but I dont know if that is it.


thanks for any help
Dennis
