If your car’s RPM readings are inaccurate, it can have a number of consequences. Most importantly, it can cause your car to run less efficiently. This can lead to decreased fuel economy and increased emissions. Additionally, it can cause your car to run less smoothly, and may even trigger the check engine light.

7.How to avoid problems with your RPM?

There are a few things you can do to avoid problems with your multimeter when checking RPM. First, make sure that the multimeter is properly calibrated.
