Update:

My Absolute Throttle is 15.3%

My Learned Throttle is 3.1% used to be 3.9. With the occasional drop to 2.7%. The occasional drop is what it was doing before it stayed on 3.1%. So my guess is that the number will continue to drop.

I wished I had the scanner the week before so I could have taken a reading when the RPMs where crazy high. As the Learned Throttle drops the RPMs are more stable and lower.

Anyone with a scanner and a clean throttle can tell me what your readings are?

PID 45 RELATIVE THROTTLE POSITION 5.9
PID 47 ABSOLUTE THROTTLE POSITION B 18.4
PID 49 ABSOLUTE THROTTLE POSITION D 18.8
PID 4A ABSOLUTE THROTTLE POSITION E 9.4
PID 4C COMMANDED THROTTLE ACTUATOR CONTROL 7.8

PID 11 & PID 47 are the same thing, I think.

That is my 2011 LT 2.2L after running for 9 minutes in 25F ambient.

Thanks for the video guille!
Have a question while im here for any of you.. My 08 has 97000 on the clock so im thinking when I replace my OE with an aftermarket CAI I will clean my TB. What happens to the gunk that runs off the sides and top of the insides? Do I try and wipe it out the best I can or just let it go wherever??

Use a lint free cloth.

Thanks Don!

Don, when is the last you clean your throttle? Never mind, just saw you have a 2.2. I have a 2.4 so I'm sure that is what the difference in the numbers are.

Retrolled, glad the video help. I wished I would have seen it before I cleaned my throttle.

Shouldn't be any difference. I cleaned it about 20K ago. I have never seen a throttle body so gummed up that it actually interfered with the butterfly, granted I have not seen that many.

Ok, last update on this. I hate it when people do not put if what they tried fix the issues they had.

After about 500 miles of driving the RPMs are back to normal. It could still be a little better, but honestly at this point its insignificant. I would say its to 98% of what it needs to be.

Took about 3 weeks of driving everyday about 4 drives a day. So if you do the math about 84 drive cycles. I think the dirtier the throttle and so the more the difference between dirty and clean is the longer it will take to return to normal.

To give you an idea. I HHR had 86k miles and throttle was never cleaned. After cleaning my idle RPMs where at 3000. After a week of driving RPS at idle where at 2400. After another week of driving they were at 1500. Now they are at 800.

I'm sure if my RPMs would have started lower it would have not taken so long to relearn.

Again, hopes this helps the next guy.

Great up-date guille2228. Yeah it sure is great when people come back and give an update. :)

And 800 rpm at idle is within factory specs, towards the high end, but acceptable.
