How To reset idle with an aftermarket Throttle Body:​

For all 2004-2006 SRT-10 Ram trucks with a Roe Racing supercharger kit. This procedure must be followed if the battery is ever disconnected or drained to the point of the truck not starting.

1. Disconnect all three PCM connectors for about 10 minutes. By doing this, you are erasing the PCM adaptive memory. The PCM is located on the firewall directly above and behind the passenger side front wheel.

2. Disconnect the TPS (throttle position sensor) on the driver’s side of the throttle body. Ensure all wire connections are correct.

3. Disconnect the IAC (idle air control motor) on the air plenum located on the passenger side directly behind the air filter. Ensure all wire connections are correct.

4. With the PCM disconnected, make sure the throttle cable and throttle linkage is adjusted properly for wide-open throttle. The driver’s floor mat should be removed as it can inhibit accelerator pedal travel.

5. After wide-open throttle is verified or adjusted, reconnect the PCM, TPS and IAC connectors after 10 minutes has elapsed from the start of this procedure.

6. Turn the key to the "on" position, but DO NOT start the engine.

7. With the drivers floor mat out of the truck, slowly press the accelerator to full throttle, then repeat. By doing this, you are showing the TPS (throttle position sensor) full throttle. Without this information in the PCM, it will not correctly calculate how to make the engine run properly.

8. Turn the key off then start the truck without touching the accelerator.

9. Let the engine idle for approximately 2-3 minutes.

10. After idling, drive easy, then progressively harder over the course of about 10-20 minutes.

11. The truck will drive differently during the first 20-40 miles because the PCM is learning the new adaptives.

Thanks for sharing, did not know this and will try.:rocker:

Yes, thank you for the info! Hopefully with Tony's new TB I won't even need it. Probably won't get to installing it till after the winter though, when I can actually drive it. Like to keep if off the dirty roads this time o' year! I gotta concentrate on some long forgotten chores this winter, like fixing my horn which has been disconnected for a couple years now. As well as installing the viper steering wheel emblem.:684: Then I can get back to the newly purchased items! :up_to_som

BBK hanging idle

I finally got around to installing my BBK TB. and of course i ran into the dreaded high idle hang. If i kicked it sightly it would idle down but was annoying! After closer inspection i found the blades must have been sticking cause the linkage was off the stop screw at high idle and was ok if i seated it. i tried to back off the screw and push the blade onto the stop and it would idle fine but would really stick then. i also noted there was alot more air going through the IAC so i decided to use the stop screw to open the TB so it wouldn't stick at all. probably 1/8" more open than unit came from BBK. reset the computer and no more problems!! idles fine and runs excellent. Just thought i would share.

Great! You had me scared for a second as I was reading, but I'm glad you got it to work. I still have to install Tony's, gotta do it soon as I have a car show at Mohegan Sun here in CT early May!

Computer resetting question:

Once I get the truck to Bowling Green this weekend towing the car on a trailer, and I get to the track and load my racing tune, should I disconnect the battery to reset the adaptives so the computer has no record of my docile driving style up to Kentucky? Or will the retune take care of that...

Thanks.

Tom, when you load the Race Tune, it is my understanding that the PCM has been "Flashed" and the adaptives are Reset at that time. So My Thought is that you would Not need to do it. :)

How do I do this? Is this the same this as the throttle valve adjustment?
Some call it throttle valve but the actual term is your IAC valve .IDLE AIR CONTROL.
This was first done when Roe Racing came out with the after market T.B and some were having a High idle issue .If you need to do this just follow instructions and don't bend a pin on your pcm and blame me for it lol.

some aftermarket TB would have to be checked to see if when you mashed your gas petal to the floor to see if TB opened the blades wide open .There is an adjustment on the cable to open more or less .
Most of the time it was ok .Have someone sit in drivers seat hold foot to the floor and you check the travel on you T.B. linkage to see if it opens all the way .

But if I have to adjust it, is this the procedure...?

Because I've done that and it worked good. I just wasn't sure if that step #4 was the same thing or not. Though I feel I have more of a different problem. When I push the pedal the first little bit does nothing, or even feels like it slows the truck down if I'm coasting. I can't launch the truck forward by giving it a quick press.
