Post found this on another website thought it would be useful to share : How to clean TB with ETC

Hemi Throttle body CleaningThrottle Body CleaningDodge Ram 5.7 Liter*Difficulty level: Easy - ModerateTools Required:
I happen to have an aftermarket CAI. If you have the Stock HEMI breather hat, you will need the necessary tools to remove - #2 Flathead Screwdriver- 1/4" Ratchet- 1/4" extension- 8mm socket (1/4)- 5/16th Socket (1/4) or equivalent Nut-driver- 3 Cans of Brake Cleaner (DO NOT USE Throttle Body Cleaner!!!!!!!!!!)- Several Clean Shop Towels (Lint Free)- 1 Toothbrush or similar sized non-abrasive scrub brush
You’ll be intimately cleaning the throttle body, that on this particular truck is actuated via Electronic Throttle Control (Drive by Wire). EXTREME CARE must be taken to avoid damaging any electronics, sensors, etc. This isn’t meant to scare you, just to warn you. As you will see, this is very easy to do if you are well armed with cleaner and know how to use a screw driver.
Step 1: Determining what you will need to remove the Intake Take a minute to thoroughly look over your intake system. Make note of all your sensors, Wires, retention brackets, etc, and make certain you have the appropriate tools.
*Step 2: Removing the intake from the throttle body Most of us have aftermarket intakes so it will vary from truck to truck, if you have the OEM Hemi hat then its just a few bolts holding it down. Use common sense and determine what steps will be necessary to remove enough of the air-box system so that you have easy access to the throttle body.*
Removing the CAI Tube from Throttle Body BEFORE you go yanking the top of your engine apart. Make note of a couple of connectors you need to remove to avoid damage.*FIRST simply use a flathead screwdriver to "break the seal" of a Vacuum line attached to CAI to pull it free with very little effort.
Removing the CAI Tube from Throttle Body The next thing to watch out for is the Intake Air Temperature Sensor, Commonly referred to as the IAT. Special care should be taken because this sensor is VERY fragile. in most cases you will probably not have to physically remove this sensor from your CAI Tube / Hemi Hat. You will likely be able to simply unplug it.*If you have ever worked on anything with a motor, you should be able to figure this out.
Depress the Locking key and wiggle the IAT Sensor harness plug from the sensor
Step 3: Removing the CAI Tube From Throttle Body Go ahead and take a second to look closely and make sure everything is disconnected and the entire intake system free.****NOTE: If you have loosened all the bolts and left them in their proper holes, PLEASE go ahead and take them ALL out before you attempt to pull the intake system off the top of the engine. THE LAST THING you want is to drop a nut or bolt into the throttle body / Intake.*Now, gently remove the remainder of your intake. It would be a good idea to have a partner watching closely as you do this because forgotten items still attached will quickly be noticed by that extra pair of eyes.*
Removing the Throttle Body Once the Throttle Body opening is secured, go ahead and look around your work area and secure all loose dangling harness connectors that we have removed to this point.
Once we start the next step, you’re going to need all of your hands and those loose dangling wires just get in the way.*If your Throttle Body is a "Drive By Wire system, you will find somewhere, a harness plug that supplies current for the motor and other essential signals passed from the computer to the T-Body.*On HEMI's, this plug is located on top, in the front of the T-Body.****NOTE: This connector doesn't work like ones you may be used to. You DO NOT push the tab to remove the plug, you will use a screw driver to pull the tab slightly away from the connector (to the rear of the plug) and this will unlock it, allowing you to remove the T-Body harness plug.

Step 4: Removing the Throttle BodyAgain, Make sure you tuck the Harness Connector out of the way.*The Next step is to identify the Bolts we need to remove to physically take the throttle body OFF of the intake manifold.*On The HEMI, You will fine VERY easily which they are. There are four 8mm bolts located at each corner of the T-Body and they face forward. You cant miss them. They have been painted GREEN
Removing the Throttle BodyUsing a 1/4" Ratchet, attach a 6" extension and an 8mm Socket.*Loosen AND REMOVE the bolts one at a time using a criss-cross pattern. Top-Right, Bottom-Left, Top-Left, Bottom-Right.*These Intakes are plastic and you want to keep the torque stress on the intake as even as possible to avoid any possibility of over stressing one particular area, resulting in a possible crack in the intake.*Once you have all four bolts removed, the throttle body will literally fall into your hand:

Step 5: Cleaning the Throttle BodyFor this, USE BRAKE CLEANEROnce again, DO NOT USE THROTTLE BODY CLEANER! Not even the MOPAR BRAND. Based on the TSB that I did this after, even THEY say to use BRAKE CLEANER ONLY because it evaporates fast, and wont damage the sensitive sensors and electronics on board the T-BodyDo yourself a HUGE favor and grab 4 cans. I used three completely and a 4th would have been nice.*Also Get a Tooth brush handy because you will need it, I assure you!Last but most important, DO NOT ATTEMPT THIS WITHOUT SAFETY GLASSES
1.Grab the T-Body and hold it with actuator motor UP so the cleaner has less chance of soaking the electronics.*
2. Hold the T-Body as far away from your body as possible and start blasting. The majority of the Coking will wash right away.*By now you have seen that Brake cleaner is some SERIOUSLY good stuff The Coking should be stripping off and pouring out of the T-body with every squirtWhen you can see that your spraying is no longer doing much Good, Its time to get the brush out...*Spray a little, Brush a little, Spray a little, Brush a little.*I have heard that you DO NOT want to press open the butterfly valve. Personally, I threw caution to the wind and pushed it almost fully open and using spraying and brushing, cleaned it spotless. The Butterfly is spring loaded and will close back just fine. Keep at it until it is clean...Once your done, allow it to sit and dry. REMEMBER, Keep the Motor Side of the TB facing UP at all time. Better to be safe than sorry.*
Step 6: Reassemble in Reverse Order
