'95 E420 - What's the correct Idle RPM?
I'm just curious as the specs. In park/nuetral my car idles at 650 RPMs (or at least that what it looks like). In drive whether the AC is on or off, it idles at 500 RPMs. Sometimes just hair above or below.
The 650 seems high to me, but that's just my opinion. Is there a way to adjust the idle, or is it solely a product of sensor inputs?
