Picked Up Car After Body Repair and Its Revving High

What to Do If Your Car Is Revving High After a Body Repair

If you’ve recently picked up your car after a body repair and noticed that it’s revving high, there are a few things you can do to try to troubleshoot the problem.

1. Check the Air Filter

A dirty air filter can restrict airflow to the engine, causing it to run rich and rev high. Check the air filter and replace it if it’s dirty.

2. Check the Throttle Body

The throttle body controls the amount of air that flows into the engine. A dirty throttle body can cause the engine to idle high.

3. Check the Idle Air Control Valve

The idle air control valve (IACV) controls the amount of air that bypasses the throttle body at idle. A faulty IACV can cause the engine to idle high.

4. Check the Vacuum Lines

Vacuum lines can leak and cause the engine to run lean, which can lead to high idle speeds.

5. Check the Fuel Pressure

High fuel pressure can cause the engine to run rich and rev high.

6. Check the Ignition Timing

Incorrect ignition timing can cause the engine to run rough and idle high.

7. Have the Car Scanned for Codes

If you’re unable to find the cause of the high idle speed yourself, you can have the car scanned for codes. This can help you identify any underlying problems that may be causing the issue.

If you’ve tried all of the above and the car is still revving high, you should take it back to the body shop and have them diagnose the problem.

Here are some additional tips to keep in mind:

• If the car is revving high when you start it, but then idles down after a few seconds, it may be due to a cold start issue. This is usually not a problem, but if it continues to happen, you should have it checked out.
• If the car is revving high all the time, it’s important to get it fixed as soon as possible. High idle speeds can put strain on the engine and transmission, and can also lead to decreased fuel economy.
• If you’re not comfortable working on cars yourself, it’s always best to take it to a qualified mechanic for diagnosis and repair.
