An engines idle speed is a programmed function. We cannot directly adjust the engine idle speed on a modern vehicle. The power control module or PCM provides all adjustments to the idle speed. Though no external engine idle speed adjustments are possible, many things can and do cause problems.
The low pressure (blue gauge) should be 35 or less at idle, regardless of the type of gas. Only if you're running a dual system, the low pressure may be between 45 and 50 at idle. The high pressure, for starters, is directly related to ambient temperature: the higher the temperature, the higher the higher the pressure.
