When the RPM gauge goes down and then up, does the engine noice change and do you loose or gain acceleration?

Also, please add your year and trim of your vehicle to your signature line. That way when you start asking questions in other areas of the forum, we all have a better idea on how to assist you. Click on "Quick Links" above, go down to "User Control Panel" and then click on "Edit your Signature" It'* pretty straight forward from there.

If the gauge is jumping around I would check grounds. Sounds like bad a connection.
