How to repair the failure of Buick gl8 air conditioner without refrigeration?

Clean throttle body and idle motor?

Symptoms: Generally, due to the air quality, there is a lot of dirt on the throttle and idle valve of the throttle body. When dirt accumulates to a certain extent, the engine will have low idle speed, poor idle stability, and stuck when refueling, so it is necessary to clean the throttle.

Solution: first clean the dirt on the stop valve and idle valve of throttle body, and then set it by computer to meet the standard.

Disassembly-free clean fuel injector

Symptoms: Because gasoline contains impurities more or less, these impurities will attach to the needle valve of the injector. Working for a long time will cause poor atomization, linear or dripping when injecting oil, and even lead to the phenomenon that the needle valve is improperly closed and often drips oil or is stuck without injecting oil. When driving, the engine will feel weak, trembling and unstable, and the exhaust gas will exceed the standard. In severe cases, the engine will not start.

Solution: When the above faults occur, it is necessary to clean the fuel injector without disassembly. At the same time, the carbon deposit on the top of the combustion chamber and piston can be cleaned together and discharged with the exhaust gas. Therefore, the power and fuel economy of the car can be restored.
