So my truck is 6 yours old now but it for sure doesnt seem that old. Weird.

Anyway, what is a simple method to raise the engine RPM just a hair, maybe +/- 75...?

When ever Im at a stop light, it vibrates a little to much. I know I could use new motor mounts but thats another story.

I think it sits around 550-625 when at idle. I have always used mobile 1 synthetic with lucas oil stabilizer since day one.

I think its really a combination of things. My tires are hard, and vibrate just a little when moving. I think over time, it has loosed up door panels which I can sometimes hear vibrating when sitting at a stop light.

I dont know what it is, I must have OCD or something....but that little vibration noise.....drives me absolutely crazy.

When is the last time you've cleaned out your throttle body? Sometimes build-up can accumulate over time in there and cause a rough idle. I took mine off and cleaned it really well and then did the throttle body relearn and it's smoother now - I have an 07 with 105k. Just did this about 5k miles ago

there is no way to do a manual adjustment since it is controlled by the tps/ecu but a programmer can/will raise it some. I have a hypertech and it raised it some but I noticed it revs up and down a little now.

Try a re-learn of your ecu by disconnecting the battery for about an hour and clean you MAF sensor.

This is the relearn I was talking about.
if you have the v6 engine this might help you out.... after cleaning maf
Accelerator Pedal Released Position Learning

DESCRIPTION
Accelerator Pedal Released Position Learning is an operation to learn the fully released position of the accelerator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time harness connector of the accelerator pedal position sensor or ECM is disconnected.

OPERATION PROCEDURE
1. Check that accelerator pedal is fully released.
2. Turn ignition switch ON and wait at least 2 seconds.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Turn ignition switch ON and wait at least 2 seconds.
5. Turn ignition switch OFF and wait at least 10 seconds.

Throttle Valve Closed Position Learning

DESCRIPTION
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by monitoring the throttle position sensor output signal. It must be performed each time the harness connector of electric throttle control actuator or ECM is disconnected.

OPERATION PROCEDURE
1. Check that accelerator pedal is fully released.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
Check that throttle valve moves during above 10 seconds by confirming the operating sound.

Idle Air Volume Learning

DESCRIPTION
Idle Air Volume Learning is an operation to learn the idle air volume that keeps each engine within the specific
range.

It must be performed under any of the following conditions:
Each time electric throttle control actuator or ECM is replaced.
Idle speed or ignition timing is out of specification.

PREPARATION
Before performing Idle Air Volume Learning, make sure that all of the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are missed for even a moment.

Battery voltage: More than 12.9V (At idle)
Engine coolant temperature: 70 - 100°C (158 - 212°F)
PNP switch: ON
Electric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine
is started the headlamp will not be illuminated.
Steering wheel: Neutral (Straight-ahead position)
Vehicle speed: Stopped
Transmission: Warmed-up
For A/T models with CONSULT-II, drive vehicle until “ATF TEMP SE 1” in “DATA MONITOR” mode of “A/
T” system indicates less than 0.9V.
For A/T models without CONSULT-II, and M/T models, drive vehicle for 10 minutes.

Without CONSULT-II
NOTE:
It is better to count the time accurately with a clock.
It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit
has a malfunction.
1. Perform EC-89, "Accelerator Pedal Released Position Learning" .
2. Perform EC-89, "Throttle Valve Closed Position Learning" .
3. Start engine and warm it up to normal operating temperature.
4. Check that all items listed under the topic PREPARATION (previously mentioned) are in good order.
5. Turn ignition switch OFF and wait at least 10 seconds.
6. Confirm that accelerator pedal is fully released, then turn ignition switch ON and wait 3 seconds.
7. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops
blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the MIL turned ON.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the
specifications.

It took me a few tries to get the throttle body relearn to work. After you've done the first two procedures you can keep trying the final relearn if it doesn't work the first time.

agred, fix the problem not the symptom. Clean the throttle body, fuel injection and UI cleaning.

no havent had time to mess with it.

I just did a complete throttle body cleaning and mass air flow I think last march 2013, I cant imagine it being that dirty. It is something I will for sure look into.

Like I said, it isnt a problem, just more or less makes me wanna scratch my eyes out. So nothing serious. :geek:

Did you reset the computer after you cleaned it?
i unplugged the + cable for about 2 hours I believe. I had to reset the ABS sensor, VDC, and I think thats all.

That's not going to relearn the system for the throttle body.

Edit: that's not supposed to sound harsh - sometimes text can seem that way. Anyway, I don't want you to claw your eyes out! But the relearn might be worth the try, plus it's free :)
