Hey I have a t320 that is sjc and in forward travel on right hand drive it drives smooth but after about 20 minutes it starts shuttering like there is something binding. It has steel tracks and still does it when track is off. There are no codes and everything on my laptop shows its all in...
I have an s250 and on the egr there is a vent hole on the bottom of the diaphragm. Has anyone seen soot comming out of this breather or is the diaphragm leaking? There is also soot inside the vacuum hoses to the temp switch. I think they should be free of soot. Does anyone know for sure?
You may also want to check to see if there was gasoline put into tank. That would let it run for 10 min or so and then power out. You should also check the fuel cap to make sure it is venting. It's 2 easy checks and could save some grief
