Hot Idle RPM Change?
My (new to me last week) '03 Ranger 3.0L stick shift hot idles about 600 maybe 650 rpm, cold idle about 1000 (45ÂºF). I spose all correct settings because it was just smogged last week. No problem with that but I'd like it to hot idle just a bit faster maybe 800-900 rpm to suit my personal style. Other than that the stock settings suit me just fine. So I'd have it done, of course, but supposing a shop would do it what are the implications.
Can they change that w/o changing all the other various settings?
What else gets necessarily changed? affected?
Would the cold idle be that much higher? Or stay the same?
Would it cause the engine rpm to float excessively when shifting? It doesn't float when cold; or does the computer control that?
This is the newest thing I have ever drove. I got it home, grabbed up a couple screw drivers with intent to up the idle, popped the hood, took one look and thought whoops! Hhhmmmm. No carburetor = better study on this. Sure enough, this formerly minor procedure is now a shop job. :-)
