What are the reasons for the car not accelerating when the throttle is fully pressed?
1 Answers
When the throttle is fully pressed, the speed does not increase. The engine operates basically normally under no-load conditions, but accelerates slowly under load, lacks power when going uphill, and still feels insufficient power when the accelerator pedal is fully pressed. The engine speed does not increase, and the maximum speed cannot be reached. These are all signs of insufficient engine power. The reasons for insufficient power are as follows: 1. Clogged air filter; 2. Improper throttle adjustment, unable to fully open; 3. Low fuel pressure; 4. Clogged or poorly atomized fuel injectors; 6. Faulty air flow meter; 7. Incorrect ignition timing or weak high-voltage spark; 8. Low engine cylinder compression pressure.
