How To: Clean the IAC Valve on dodge RAM?

3.9L, 5.2L or 5.9L magnum engine rev up and down during idle while in park or netural? If so, the problem is a dirty IAC. Here's the process to clean this IAC to keep your engine happy with a nice idle rpm and avoids wasting fuel too.

A sample look of a 3.9L, 5.2L or 5.9L magnum engine with the van's dog-house removed.



Here's the jewel of the IAC. Notice the driver on the left mounting screw.



Just remove the connector out of the way.



Rats. The fuel bridge is in the way to get the second screw off.



OK, I'll use a longer driver socket and a pair of pliers to get the screw loose.



Now, with the flex drive over the bridge, the screw turns quickly. You may use what ever tools you have to get at that screw too.



*** NOTE ***
NEVER move the IAC brass probe more than 1/4" in travel while cleaning or handling. !!?!! Right now the picture shows it all black.

Ah, here's what the IAC looks like. OK, think clean thoughts here.



Up close all dirty ...



My cleaning bench.



A cotton swab and clean rag.



The IAC cleaned up really good.



Ah, but wait, there is more!!! The TB port is dirty too!





One clean IAC port. That's how it's too look. OK, clean thoughts here too.



Alright, just put the IAC back into the hole, drive the screws and plug in the connector.
