What are the consequences of not cleaning the throttle body for a long time?

[LaRose]

Not cleaning the throttle body for a long time can lead to increased fuel consumption, increased carbon deposits, unstable idling or abnormal fluctuations in the vehicle, and over time, it may even prevent the car from starting. Steps to clean the throttle body: Turn off the ignition switch and remove the negative terminal of the battery; disconnect the throttle cable, intake hose, and the screws fixing the throttle body; use carburetor cleaner to clean the throttle body, and for areas that are hard to reach, use a cotton swab to wipe; after cleaning, reinstall the throttle body in the reverse order of disassembly, and test whether the cleaned throttle body allows smooth air intake. Introduction to increased carbon deposits: When there is excessive carbon buildup in the engine, it can cause difficulties in cold starting, unstable idling, poor acceleration, backfiring or jerking during rapid acceleration, excessive exhaust emissions, increased gasoline consumption, and increased oil consumption.
