Diesel idling too fast. Diesel idling too slow. Diesel shaking at idle. Transmission jerks with shifting from Park to Drive. These are some of the symptoms that might indicate your engine's idle speed is not adjusted correctly. With Kent's detailed video instructions, this long-reach special tool, and a digital tach you will be able to get it right in no time.
PLEASE NOTE: The digital tach is a very handy tool to have in your shop. It will work on any gas or diesel engine and even small engines like lawns movers, etc. The tool is specific to the idle speed adjuster for the 1977 to 1985 diesel injection pumps as shown, but the 14mm and long 3/8 inch extension can be used in other places as well.
