How to clean Buick 2.5 automatic throttle and use it to reset after cleaning? How to avoid idling too high or too low?

The accelerator of Buick 2.5 automatic transmission is an electronic accelerator. Precautions and methods of cleaning: remove the throttle, pull the throttle to full open by hand, spray the throttle cleaner on cotton cloth, and wipe the dirty part of the throttle until it is clean. At present, it is found that some car owners are used to cleaning the throttle body on the engine, or removing the throttle body and spraying cleaning agent into the throttle body for cleaning. Because the cleaning agent is a highly permeable liquid, during the cleaning process, part of the cleaning agent will flow into the actuator through the throttle blade shaft, resulting in the corrosion of the sliding resistance of the internal sensor, and the system will report the occurrence of fault codes such as P2 135 throttle 1-2 position correlation. The engine control module (ECM) reads the air flow of the throttle body to ensure the correct idling operation. When the air flow of the throttle body changes, these values must be re-read due to cleaning or replacement. If the learned value does not match the actual air flow, the idle speed may be uneven or a DTC may be set. In this case, it is necessary to use the automobile computer diagnostic instrument to match the throttle and keep the idle speed stable. The method of resetting the idle speed of the throttle: use the automobile computer tester-enter the GM system-enter the relevant model year car-enter the engine system-enter the component inspection-enter the throttle reset-reset-and confirm. If it is a non-electronic throttle car, there is no need to match the throttle after cleaning the throttle.
