Changing Base Idle 92 5.0 Engine

so ive read some threads on how to change base idle seems easy enough, I shouldnt have an issue changing base idle to around 1000-1100 right?

If you do set it higher than 750 RPM, the computer will no longer control the idle speed. That may or may not be a problem depending on your driving habits. It will also probably set code 13, but that should not affect how the car runs otherwise. It should not set the CEL (Check Engine Light) but may be present when you dump the codes.

A slight decrease in gas mileage and a slight decrease in engine braking when downshifting - it may not even be noticeable.

Basically you are disabling the ability of the computer to control idle speed. The IAC motor will always remain closed in attempt to lower the idle. You will also have a check engine code stored for it, but this code won't display the engine light in the dash
