Idle Tuning - Base table

In the Base table we see the four conditions our engine can be operating at while idling. We agreed to only focus on the two without the AC to make things a bit easier.

1. In Gear AC off
2. in Gear AC on
3. P/N AC off
4. P/N AC on

Once warmed up we should be in the green zone so our RPM should be 550 in Park and 525 in Gear.

Note: My numbers are based on a 2001 GMC Sierra 4.8L 4L60e 2WD, your numbers may vary.
