Hey guys. Jm having trouble with my td42t. While driving normally i loose all throttle response. The engine is still running- engine braking and no warning lights come on. If i change down a gear or two and dump the clutch while still in motion while working the throttle it usually comes back into life and starts to accelerate again. Plenty of fuel in tank. Air element clean. I am suspecting a loose vacuum hose. Any body experienced this before or anything similar? Im 350km from home.
