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.
This assumption leads to the theory of. â85th percentile speed,â defined as the speed. 85% of drivers are moving at or below. Many studies have shown that despite the posted. speed limit on a given section of road, most. drivers tend to travel at a speed that is comfort-. able relative to roadway conditions and, at that. speed, the least amount of congestion and. crashes will occur.
