EPC light is on. First, the throttle body is dirty and has carbon deposits. Clean the throttle. Secondly, the air intake system causes vacuum leakage. Check whether the connection of each vacuum hose is firm or broken. At this time, the theoretical values of the air flow rate and throttle opening (how big the throttle is and how much air is admitted) checked by the engine through the air flowmeter will produce errors, which will make the mixture too lean. These two conditions will basically make EPC lights light up.
