Just my opinion, I'd check for applicable trouble codes, first. Some of the national brand auto stores will check codes for free. If you want to check codes, yourself, at the least, you need an obd2 code reader that will check po codes as well as manufacturer specific codes. See if anything points to tac/throttle actuator control?
There are also accelerator pedal position sensors that you need to check. If you want to clean throttle body, that's fine.

I have a 2006 Chevy Trailblazer LS I just replace the throttle body I was having problems with low Idle and when I would turn on the AC the car would shake I'm still having the low idle with the air...
Sounds like a idle control valve or sensor the sensor has a pintle with a spring from the housing to the tip of the pintle can't be more than 1 1/8 check yours or buy a new one but you still have to measure the new one before you put it in then drive the car at 40mph for 10-15 seconds Straight so it can reset itself

2004 Trailblazer 6 cyl. idles too low and sometimes will kill but runs great. A scan code of P0606 comes up which relates to the pcm but this has been going on for over a year and it helps idle better...
The low idle could be caused by a dirty throttle body (TB). Take the TB off the intake and clean it thoroughly front and back sides. While doing the cleaning, disconnect the battery to reset the PCM. This will allow it to relearn to the cleaned TB.
As far as the P0606 code, it is possible that the PCM only needs to be reflashed (memory reloaded). This can only be done by a GM dealer.

2004 trailblazer when i turn heat on truck vibrates and turns off. was told it could be a sensor but dont no where they are or which one.
Time to clean throttle body, a dirty throttle body will cause low idle and stalling. Make sure to disconnect the battery during the cleaning process, this will reset the PCM (computer) so it can relearn to the cleaned throttle body.

2006 Chevy Trailblazer is mis fire on cylinder 1 and it is idling too low. Can you tell me what is wrong?
Not without seeing it, but...
Coil pack are common on those. If you have the in-line 6 cylinder, it would be the front cylinder. While idling, unplug the harness for the coil pack on #1, if you have no change in the way it runs, your problem is in that cylinder. Try another to see the difference, as it should stall. I have "swapped" them around to verify the issue.

P2176=Throttle Actuator Control System - Idle Position Not Learned
Did you use all you old sensors,or is some of them from the new engine,I would swap out the IAC sensor or check for wires not hooked up.
If it can't relearn to idle the Idle air control might be different then your old one,but its not registering with the computer

Idle problem on a 2006 chevy trailblazer 4.2
The code indicates an issue with the Throttle Actuator control. This is a little motor on the throttle body that opens the throttle plates at idle. That control motor may be bad and thus, causing a low idle.

I hope this helps.
