My car is a used car, Toyota Camry 2.4 in 2005. Recently, it was found that the engine wobbled when the car was hot. Cleaned in the repair shop, throttle,

1. Completely remove the carbon deposit on the intake valve (remove carbon deposit).

2, gasoline pump pressure detection

3. Check whether the fuel injection quantity of the fuel injector is consistent.

4. Check the ignition coil and cylinder pipeline for aging and leakage.

Needless to say, there will be a comprehensive physical examination after the second-hand car is bought back.
