Ok,

im trying to see if i need to bring to dealer after i clean my throttle body.

my mechanic said that i do have to do it.. but i dont know much.

please advise

this is an 03 automatic coupe.

 

it is highly recommend to perform whats called an "idle air volume learn". the idle is directly control by the ECU via the electronic throttle. over time the ECU will slowly adapt to all the junk built up on the throttle plate. but as soon as you remove it the computer will not be able to adjust, and thus driveablity is affected.

 

ok can you link me? i mean im not that very knowledgeable about cars and such. but ill try my best to learn

but do i have the opton to bring it to dealer and how much do you think it will cost?

 

ok looked it up

Idle Air Volume Learning (Throttle Position Learning)

It is better to count the time accurately with a clock.

1. Perform “Accelerator Pedal Released Position Learning”.
2. Perform “Throttle Valve Closed Position Learning”.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Confirm that the accelerator pedal is fully released, then turn ignition switch “ON” and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications.



wow.. this required extreme timing and testing..

 

Much easier with Consult ... let the computer do the work.

 

u best take it back to the dealer

 

anyone know what is the price range to get this done?

 

Wait so all you want to do is reset you ecu? If so just do the steps you already listed. It is very easy but the timing has to be accurate. I did it yesterday after installing my ground kit from SxExCx. Very easy to do but the timing has to be accurate.

 

this does not reset the ECU. this procedure allows the computer to find the correct idle RPM and calculate the amount of air (throttle opening) needed to sustain this RPM.

 

Does this even help the car at all? Who has done this? What is the cost?

 

this is recommended anytime the throttle body is removed or cleaned.

if you aren't experiencing issues then you can probably just let it slide...

 

Thanks.

 

I just cleaned my TB and didn't do the reset and have no issue - idle is the same as it was, maybe 50 RPM higher. I did remove the throttle body harness connector before cleaning the TB, though.

 

Where can we find this consult?

 

consult is the scan tool they have at the dealership. they were going to charge me 120$ to do it there but they gave up trying on my car because after i replaced the TB i had no idle.
