Q: What’s wrong if your car starts but does not have refs
Answer:
If your car starts but doesn’t have revs (meaning the engine is not revving or responding to the accelerator), it could be caused by a number of issues. Here are a few possible reasons why this might be happening:
1. Clogged air filter:
A dirty air filter can restrict airflow to the engine, causing it to run poorly or not at all.

2. Faulty throttle position sensor:
The throttle position sensor tells the car’s computer how far the accelerator pedal is pressed. If the sensor is faulty, it may not send the correct signal to the computer, which can cause a lack of response from the engine.
3. Bad fuel pump:
The fuel pump delivers fuel to the engine. If it is not working properly, the engine may not receive enough fuel to run correctly.
4. Failed mass airflow sensor:
The mass airflow sensor measures the amount of air entering the engine and tells the computer how much fuel to inject. If the sensor is faulty, it can cause a lack of response from the engine.

5. Ignition system failure:
If the car’s ignition system fails, it may not be able to ignite the fuel in the engine, causing a lack of response from the engine.
These are just a few of the possible reasons why a car may start but not have revs. It’s important to have a qualified mechanic diagnose and repair the issue to prevent further damage and ensure that your car is running safely and efficiently.
