First off - thanks for a great website with tons of useful info. I bought a 93 W250 Ex Cab Auto with 190K (stock) two weeks ago and am very happy with it so far. However - twice in the past week, when the engine is cold (outside temp 20, truck plugged in) the throttle wouldn't move more than a 1/4 inch. After the truck got warmed up it gradually freed up. Linkages don't seem to be binding. This only happened twice and otherwise runs great. Any idea whats up with my ride? <br>Thanks in advance.

 

The next time it does this. Check the throttle assembly on the pump itself. Alot of times, moisture will get into the throttle assembly and freeze. Just a suggestion, but worth looking into.
