Discussion:
High Idle

Hello, I am working on an 8Fgcu25 serial 19741. Unit has an idle of 1275 according to the multifunction display and clearly is too high. No codes. No broken wires that I can find. I have checked all that I know having worked on these units since they were new. I haven't ran across this issue to this point. Has anyone seen this issue? Drives as it should, the only time it can idle down is unplugging the throttle body. At that point, there is a code and obviously no throttle response.
Thanks

Check for vacuum leaks I had one with a high idle where the PCV valve was disconnected from the valve cover

Check for any vacuum leaks. I have seen the PCV hose come off the valve cover and cause a high idle. Also you can adjust the idle via the multifunction display however I believe you can only go from 650 to 750

Fact of the week
In March 2002, identical twins in Finland died on the same day in similar accidents within hours of each other. A 70-year-old man was killed by a truck while cycling; hours later, his twin brother was killed by a truck on the same road, about a mile away, before the family had been informed of the first accident.
