Car Forum / Ford / Ford Trucks / March 2006'01 Ranger Fast Idle
Recently I noticed that my Ranger idles somewhat fast when it is cold (1,300-1,400 RPM). After the engine warms up the idle goes back to normal (800 RPM). Does anyone have any ideas what might be causing this?  SignatureMike Schumann > Recently I noticed that my Ranger idles somewhat fast when it is cold > (1,300-1,400 RPM).

Every vehicle has one, and when the engine is cold it goes to a cold start mode, and has a high idle till the engine reaches a certain temp. Ir is very normal... Expect to see it if the temp is below 40 deg F the first time you start it. If it does it on warm days, then you need to have the comp checked out. |
