Re: High Idle Service Kit?
It seems it's a recognized problem by Ford on 98-00 ranger/sho. I have had the same problem for the last couple of years and nothing I've done fixes it. I've cleaned and cleaned and replaced parts to no avail. I'm going to try and find the part which during a google search says it runs about $17 at the dealer. But first I'm going to try this solution I found on the ranger station posted by greenpus:
"Here's my suggestion.
This is only my opinion and cleaning the IAC on these newer models (98-newer) is pointless even though many say it helps. I've gone through so many IAC's on my 2000 Ranger and cleaning the IAC does nothing.
Here are my suggestions for the common problem of fast idle which is consistent of a bad IAC.
First off ignore the tech bulletin that everyone posts in regard to replacing the connector on the TPS. It will probably fix your problem but there is a cheaper and better way that don't put the extra cash into Ford's pocket for a piss poor design.
Buy electronic contact cleaner at Radio Shack or an auto parts store. Get the kind that cleans only and does not lube. Also pick up a tube of dielectric grease.
Disconnect both connectors for the IAC and the TPS and spray the contact cleaner on both ends and reconnect and disconnect both several times to clean the contacts. Spray liberally again and again connect and disconnect several times to clean contact pins. Let the connectors hang disconnected for 10 mins so the contact cleaner fluid evaporates.
Fill the pin holes in both connectors with dielectric grease. Don't be scared. Use a lot of the dielectric grease. Connect connectors. This cleans and protects the pin contacts so you don't have to replace the connector as stated in the tech bulletin.
Drive the truck and verify the fast idle has been resolved. You might notice erratic idle for a few mins because of the process the computer has to go through to relearn the idle trim. Best way to relearn the idle trim is to allow the truck to warm up and do some city driving in stop and go traffic. It really doesn't take that long. Don't waste your time disconnecting the battery.
If the fast idle issue returns then replace the IAC"
I'll let you know what happens.
Update: I started checking for the part online with different Ford suppliers and it runs about $110 not $17 like I read in a couple of posts. So I'm definitely going to try the above first.
