High idel


You may have a bad control valve or regulator. Did you adjust the idle properly?

1. Disconnect the connector on top
2. Adjust idle to around 650-700k rpm
3. Reconnect the electrical connection

After reconnecting, the idle should jump up around 700-750k rpm.
The idle screw is fail safe setting in case the ecu cannot set the idle. The rpm's set by the idle screw are supposed to be below the ecu/stock idle.

If this doesn't work, you may have a dirty or bad Idle Air Adjuster and/or Air Regulator. For information on cleaning that, you can refer to this page http://s95014253.onlinehome.us/63104/157335.html

You can test the IAA by supplying power to the plug with the car off. Listen for any clicks or humming. That will signify that it still may be working but is possibly stuck. The Air Regulator is for high idle for warming up your car. It has a bi-metal spring inside that rotates a disc closing off an airway to bring idle to normal after a couple minutes. If it dies it will stay open and give you permanent high idle. If it gets clogged usually no high idle for warm up.
You can remove it and peer through the end. If you see a thin sliver of light, it's open. Connect 12 volts + & -, wait a few minutes and see if it's now closed. If not, it's likely dead. It can be opened and cleaned if that's the issue.

96 f-150 idles really high


I just solved this problem on my truck after fighting with it for 2 yrs. Mine is the 5.0 though, check your PVC valve and replace if it is bad. After that Take off your IAC and spray down with carb or brake cleaner and scrape all the carbon build up out of it and work the spring inside. you gotta really clean it out though! After that if it's opening and closing easily put it back together and it should work! you might have to adjust the idle a bit to get it all the way. But after doing this my truck went from a 2000 rpm idle down to about a 700! I hope this helps you!!
