What are the reasons for the lack of acceleration in the Honda Spirior 2.4?
1 Answers
The lack of acceleration is mainly due to insufficient engine power. First, use a diagnostic tool to check the PGM-FI system and A/T system, and no fault codes were found. The speed in both D and R positions is 2500r/min, which is normal. Conduct a time lag test: 1.1s in D position and 1.2s in R position, with normal responses in all gears. A basic inspection of the engine and automatic transmission also yielded normal results. More relevant information is as follows: 1. Necessary conditions for normal engine operation: Not only sufficient fuel supply but also air is required. A clogged air filter or throttle system can lead to insufficient air intake. 2. Check the electrical system: An internal combustion engine requires spark plugs to ignite the fuel entering the engine, so the condition of the spark plugs directly affects the ignition state. Spark plugs are consumables and need to be replaced after a fixed mileage.
