停車轉速突變

06 行版
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.

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。

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.
其實點解洗完會出現高轉數問題?純粹想學下野
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.
