早前一日之內, 停燈位時, 死了三次火. 之前未試過. 死左之後, 撻返匙就無事. 搵朋友幫我整整, 佢話有機會蝴蝶掩要清潔, 佢扭開氣喉, 噴左專用清潔劑起風口位, 再P波踩油噴左好多白煙, 過一陣便正常. 不過, 問題來了, 以往我停車時大約得7百幾轉, 但宜家變左1000轉, 我用OBD去測耗油量, 平時停車約0.8L/hr，但宜家變左1.6L/hr, 同埋馬力好似大左咁, 踩BRAKE時, 踩得淺架車都繼續加速, 究竟發生咩事? 求各位師父指教.

Do the idle learn procedure whenever you do any of these actions:

-replace ECM/PCM
-Reset ECM/PCM
-Update ECM/PCM
-Replace or clean throttle body

Procedure

Make sure all electrical items (a/c, audio, lights, etc) are off.
Reset the ECM/PCM (pulling the power by unplugging the battery works well).
Turn the ignition switch ON (II), and wait 2 seconds.
Start the engine. Hold the engine speed at 3,000 rpm without load (in park or neutral) until the radiator fan comes on, or until the engine coolant temperature reaches 194 F (90 C).
Let the engine idle for about 5 minutes with the throttle closed. (NOTE: if the fan comes on, do not include its running time in the 5 minutes.
The biggest this I can say: be patient. If you don't get it just right, you may need to do the procedure a second time. Also, keep in mind that an erractic idle can also be caused by a vacuum leak.

Hi, SAMMY. Thank you for your info.
I want to clearly understand your procedure.
1. 熄晒所有電用品
2. 起電箱扭走兩個正負極，兩秒後駁返（係咪呢個時候駁返？）
3. 撻匙到點火II, 兩秒後撻著
4. P 或 N 踩油到3000轉
5. 等風扇著或水溫到90（但我點睇？）
6. 熄匙等5分鐘（係熄匙定著住唔踩油）

請指教。謝謝師父。

洗完蝴蝶掩 9成都會出現高轉數問題..簡單d可以比車房篤電腦reset, 或者試下森美個方法

作者: keithhui 時間: 24-12-2015 17:01

其實點解洗完會出現高轉數問題？純粹想學下野

作者: keithhui 時間: 24-12-2015 17:05

另外，死火同蝴蝶掩有什麼關係？想瞭解下。

我試了斷左電約兩分鐘, 再撻匙. 佢初初都係約1200轉, 但慢慢下降至到700轉.
回復正常! 謝謝大家幫忙.

"... Our cars are equiped with an adaptive PCM that "learns" our driving behaviour and adjusts tables to match. When you force open a "fly-by-wire" throttle body, the rest zone goes out the window and the idle goes to hell. The only way to fix this is to either get the PCM flashed to stock or to allow the PCM to find the normal idle again. ...."
