Engine Performance problem
1997 Ford Ranger 4 cyl Two Wheel Drive Manual 97000 miles
97 ford ranger starts and drives fine except when I coast to a stop the idle stays revved up a bit, then when I come to a full stop it settles down to normal. I'll take off, go to shift and the engine revvs up some, i'll shift gears, let out the clutch and the truck sort of lunges a little bit. It revs and idles high then settles down to normal again.
No engine light has come on.
I'v looked under the hood for loose hoses, clamps etc. Don't see anything noticible.
Read online about the EGR valve, oxygen sensor, Idle speed control motor and have identified all of those componens but I don't know what exactly they do or if
any of them need to be replaced.
Appreciate any help
have the same problem?
