Okay, I finally got around to cleaning my EGR ports and I know there is already a write up but I thought I might add a little to it so here goes.
This should clear the EGR Lack of flow codes.
Here is a list of tools and supplies.
Tools:
Parts and materials:
First thing you need to do is Remove the Resonator which is the Intake tube with the V8 and over head cam markings.
Now that the Resonator is out of the way we can take the throttle body off. There are four bolts that hold it on, remove these and it will come off. You don't have to remove the the throttle linkage or unplug the TPS but it is not that hard to do so and it makes more room but this is up to you.
Once you remove the Throttle Body You need to start removing vacuum lines and such connected to the Throttle Body Adapter. Be careful with these so you don't break any and if you need to take a picture or chart the locations down so you can be sure to put them back where they were.
When you remove the above lines and part it will look like this.
Don't forget the other side.
Now you want to unbolt a little bracket that is attached to the Throttle Body Adapter and move it back out of the way. This requires removing two 10mm bolts.
Once you remove the two bolts push it back out of the way like this.
Now you can unbolt the Throttle Body Adapter. There are four 8mm bolts spaced in a square fashion like the Throttle Body.
Once you remove the Throttle Body Adapter you can now see the EGR ports you need to clean. There will be a C shaped channel that will be completely gunked up rendering the EGR useless. Here it is Gunked .
To remove all this Gunk you need to first place a rag in the intake hole to prevent anything from being knocked down in. The you can use a screw driver or pick to scrape the gunk out while you use a vacuum cleaner to suck it all out. There is a port that goes from this channel to the EGR that you will need a stiff wire like a coat hanger to clean out but mine wasn't really gunked up so yours may not be either but I would make sure. Once it is all clean it will look like this.
Now you need to clean up all the Gasket mating surfaces before install. Here are pics of the Throttle Body Adapter and Throttle Body.
After you clean up all Gasket mating surfaces you can now reassemble everything which is the reverse of removal. When you tighten the bolts make sure you tighten them evenly like you would lug nuts and don't kill them. They need to be tight but these parts are aluminum and if you over tighten you can strip out threads or even break these parts so be careful! And all the electrical connections you unplugged can get some dielectric grease.
Once I was all done I noticed an increase in power and performance (nothing spectacular but enough to notice). I don't really know yet for sure if this cleared my code because I removed the Check Engine Light bulb so I will have to update this at some point and let you all know when I either put the bulb back or get the codes read.
Also here is a video to watch covering all this.

Okay, I hope this was helpful, informative, and enjoyable.
