Kia Barriga can't afford to throttle. Is it boring?

This is caused by lack of motivation.

The lack of engine power and poor acceleration are generally caused by low fuel pressure, poor fuel injection by injector, low ignition pressure or energy, incorrect ignition timing, low cylinder compression pressure and blocked exhaust pipe.

First check whether the throttle can be fully opened according to the situation. Two. Check the air intake system for blockage or air leakage. Blockage or air leakage will affect the intake efficiency of the engine, resulting in the decline of engine power and acceleration performance. Third, check whether the exhaust pipe and three-way catalyst are blocked. If the exhaust pipe is blocked, the combustion speed of the mixture will be reduced. Fourth. Check whether the fuel system supplies oil normally. Whether there is too much carbon deposit in the injector and whether the oil pressure regulator is normal. Check whether the ignition system and ignition components work normally and whether the ignition timing is normal. Whether the spark plug electrode gap is normal and whether the ignition coil leaks electricity. 6. Check whether the cylinder pressure is normal.
