Honda Accord engine is weak. Idle jitter. Especially when the air conditioner is turned on uphill, it is even more powerless to pull. Changed the spark plug and washed the accelerator.

Have you considered the cause of oil? According to the analysis of most maintenance cases, I found that I changed a lot of accessories, and the symptoms were solved after changing to a gas station. You know the oil quality in China! It is suggested to rule out external factors before considering the car. If the oil previously added in PetroChina is changed to Sinopec next time, and vice versa. If it is not caused by external factors, it may be the ignition system (ignition wire, ignition coil) fault and the fuel system fault. It is recommended to go to a professional repair shop for a detailed inspection to determine the reason.
