12 Buick excelle 1.6 manual idle throttle nozzles are all cleaned and do not work. Have the spark plug and high-voltage wire been replaced?
Due to too much carbon and dirt deposited in the engine air inlet, the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle intake air volume, resulting in too rich or too lean mixture, abnormal combustion or jitter or even failure to start the engine after starting. It is necessary to check the working state of the fuel injector and whether the pulse width of the fuel injection quantity meets the standard. Also use an endoscope to check whether there is too much carbon deposition in the intake valve and combustion chamber.
Check the working conditions of spark plugs, high-voltage lines and ignition coils. Poor ignition system and poor spark plug misfire can also lead to such failures. The solution is to check whether there is too much carbon in the spark plug and replace the spark plug. If you have cleaned the engine carbon deposit, cleaned the accelerator and changed the oil pad and spark plug, you still find that the car body is shaking at idle speed. It is recommended to check whether the oil supply pressure and intake pressure sensors are normal. If the oil supply pressure of the oil pump is abnormal or the value of the intake pressure sensor is wrong, it will cause the body to shake. The solution is to check the oil pressure and replace the parts if necessary.
Excelle's idle jitter is useless to clean the throttle and idle motor and replace the steam filter. Carbon deposition cleaning is mainly prevention. In order to clean up the carbon deposit, it means that a large amount of carbon deposit is produced, which violates the principle of maintenance first and maintenance second. When the amount of carbon deposit is large, it is maintenance.
Maintenance will naturally be dismantled, but maintenance is the same as usual, and there is no need to dismantle it. The sooner you start, the better. After all, over maintenance is better than under maintenance. Starting from the new car 5000, 10 tank oil uses disposable general fuel additives.
10W is stable, and I don't have other people's idle jitter or engine oil. BMW is a good car. The key is scientific maintenance, which doesn't cost much.
