hi, how would i go about setting a high idle setting on my 1994 ford f350 up?

 

Yeah, it seems that mine used to have a high idle but this year I havent had it.....or maybe its just me....

 

At Cold Idle Solenoid:

1. Place transmission in NEUTRAL or PARK.

2. Start engine and bring up to normal operating temperature.

3. Disconnect fast idle solenoid from wiring harness.

4. Apply battery voltage to solenoid to activate it.

5. Rev engine momentarily to set solenoid to activate it.

6. Check fast idle speed setting. Fast idle rpm should be 825 ± 25. Adjust to specification by turning solenoid plunger in or out (Figure 11).

7. Rev engine momentarily and check fast idle rpm. Adjust as necessary.

8. Remove battery voltage from solenoid connector and connect to wiring harness.

 

Inspect this wire, make sure it is still on the temp switch.



That switch controlls the timing advance and fast idle.
The wire is rather easy to knock off when you are working on glow plugs, return lines, IP wiring or the alternator.
