Q: Rotor that the Serpentine belt rotates on on a 2003 F150 pauses for a second then continues. Is this an issue? I have a video.

Hi there. When your model Civic begins to experience this it it is the first sign of transmission failure. The transmission fluid needs to be checked to see if it is at the right level. If it is check the...

You may be having a normal condition. When you accelerate hard, you are dumping a large amount of fuel into the engine and then stopping quick and shutting the throttle. You still have all that fuel in the engine and...

This sounds like potentially either a loose crankshaft pulley bolt or potentially stripped threads on this bolt. Either way, this has likely caused a problem with timing (https://www.yourmechanic.com/services/adjust-ignition-timing) and potentially a variety of other issues. Since you can't get the...

Hi, thanks for writing in. The Lexus brand is owned by Toyota. Toyota manufactures every part of Lexus automobiles. Lexus is Toyota's luxury brand. This is true for many car manufacturers. They will have a basic brand that is more...

Different than the Check Engine Light, the Service Engine Light is typically triggered when a predetermined service interval has been reached. There are dozens of service schedules that could be coming up including oil (https://www.yourmechanic.com/services/change-oil-and-filter), transmission, battery (https://www.yourmechanic.com/services/service-battery-cables), ignition system...

As you may know, trouble code P0420 (https://www.yourmechanic.com/article/p0420-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-1-by-jamahl-walker) relates to the inefficiency of the catalyst system, which detects the presence of oxygen in the exhaust gases. This can be caused by failing O2 sensors that need to be replaced. This...

Hello. In order to remove the oxygen sensors, you will likely need an offset oxygen sensor wrench. An offset oxygen sensor wrench will be compact enough to fit into low clearances but still provide enough torque to break the sensors...

In order to verify the leak you will need to have the cooling system pressure tested to see if it is just a hose or the radiator is leaking. This way you do not replace good parts. You may have...

There are a couple of things that may have caused that kind of shaking or jerking. If this is related to the transmission, this may be caused by low transmission fluid or a faulty shift solenoid. The traction control light...
