I have a 2002 2.3 auto. It idles @ 1000-1100rpm. It will not adjust down any lower. BUT, when I am coming to a stop or coasting and I put it in neutral, the idle will drop to 6-700 rpm until I come to a complete stop. At complete stop it immediately returns to 1000 rpm. So, I know this vehicle will idle at a lower rpm, how do I get it there? Screw adj. on throttle body will not do it.
I scanned forums for some answer or indication of what it might be, no luck so far.
What is it about the ranger that would make the idle lower when it is rolling in neutral and go back to 1000rpm as soon as it stops? Lower by 3-400 rpm?
