Throttle Body Cleaned
I just went out and took a peek. It looks pretty straightforward, disconnect all the lines, 4 bolts, then the throttle linkage. That is what Im caught up on, the linkage. Maybe a link to that DIY? I can't find it for nothing....
I had both carb cleaner and brake cleaner but since the thread said to use the brake cleaner I did but I was very careful to stay away from the electronics. I used a non-napping towel when I did the intake behind the throttle body and I wiped the crud out of there. It was hard with my fat hands but I got er done.
I disconnected my CAI hose from the throttle body, unplugged the wiring harness on top of the throttle body, and then pulled the 4 bolts and the throttle body comes off in your hand. Clean it really good using brake cleaner and stay away from the electronics on the throttle body. Reassemble in reverse order.

I usually copy the posts over to a word document for easy printing and saving. This is what I saved from the post:
getting to the throttle body(this was done on a hemi with stock air intake
1 disconnect thenegitive battery terminal
2 disconnect the wire from the sensor on the big plastic cover that says hemi 5.7 on top of the engiene its at the front of the cover to the left hand side just unplug it
3useing the screwdriver undo the tube from the airintake box and the plastic cover a few turns on the clip and the tube will just pull out
4 get the 10 mm socket with the extention there is two bolts that holds the big plastic cover inplace one at the front left and the other on the right its easy to find once lose the cover will just pull off
5 now we see the throttle body unplug the sensor that is at the top as you look at it from the front you will see 4 bolts holding it inplace
get the 8mm socket and extention and remove to 4 bolts the throttle body will just pull off and you will think its not too bad but when you turn it around you will probably see its black with gunk
cleaning
put throttle body in the plastic bowl and spray lightly with the brake cleaner useing the shop towel take care and clean around the whole throttle body but take special care not to catch the sensor when cleaning i used a quetip when cleaning around that once clean sit it to the side and let it dry
while it was drying i clean the opening where the throttlebody goes with a damp shop towel (make sure the towel is just damp with brake cleaner not soaked ) wipe around the opening where the throttle body goes and clean the air intake tube and may as well clean the air box while your at it
time to put it all back together
its just the reverse from thakeing it off when i put the throttle body back on made sure to tighten the 4 bolts even finger tight the top left bolt then bottom right then top right then bottom left then i used the socket and niped them up useing the same pattern till it was tight
this is also handy for the error code p2175 that i was getting and it seams to have fixed the problem for now just wish i took some pics to go along with this but i forgot the
whole prosess takes around 30 mins from start to finish easy to do as well

You can thank the gov'ment and all their emissions crap for that! The EGR dumps right behind the throttle body and is why the back of that plate is so crudded up.
I clean mine every 15,000 miles and it's filthy every time I do.
Glad to see the DIY's and the FAQ section are helping y'all out...
