It sounds like you may have a dirty or failing idle air control valve. The idle air control valve monitors the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and...

Hi...the codes appear to implicate different vehicle systems. As far as the required services, such will depend on exactly why the particular code has set. For example, resolutions of P0420 range from replacement of the converter to simply bad wiring...

I would not recommend changing the fluid or getting a flush on the transmission since you are already starting to have a problem. A service may make it worse at this point. I would have the transmission checked by a...

Hi there. If there is fuel and the engine will not start up when it is at operating temperature, then either the crankshaft position sensor is getting hot and not making a connection or the coolant temperature sensor is malfunctioning...

Hello - it is unlikely a bad intake manifold gasket will cause a blown head gasket on a Prius (different story for GM V6 engines). It is possible that a failing head gasket can cause a misfire over time -...

Hi there - the symptoms you describe indicate a thermostat that is not properly keeping engine temperature at the correct operating level. The thermostat should restrict flow as necessary (stopping or running the heater) to keep the engine at operating...

It sounds like you will need to have the starter checked. You'll need to check if the click is coming from the starter solenoid on the starter or the relay in the power relay box in the engine compartment. Also,...

This grommet is on the valve cover if I remember correctly and typically a small piece of material falling in would not be a big deal. It is best not to start the engine and attempt to have the piece...

You may have a bad tire or something that is loose on the front end. I would suggest having a mechanic lift and inspect the tires and front end to see if there is a front tire or axle problems....

Hi there. Check the camshaft position sensor and see if its plugged in. If the sensor is plugged in and the engine will crank, then the camshaft could be out of timing and needs to be reset. If the engine...

Like your engine, your transmission needs fluid in order to operate safely. It lubricates parts, reduces friction, prevents premature wear and tear, and more. It’s vital that you keep an eye on the level of fluid in your transmission, and...

The shakes can be the front wheel bearings loose and the front brake rotors warped. The vehicle front end has to be lifted and bearings checked. The rotors will only cause the shake when stoping. You will need to have...

This is a fuel supply problem. Fuel pressure will be the key indicator for which component of the fuel system isn't performing as needed. Check to be sure the fuel pump relay is good, and the fuel pump is running...

If your vehicle's check engine light illuminates, there is a malfunction that should be diagnosed and repaired. If you request a check engine light diagnostic, a certified mechanic from YourMechanic would use a code scanner to retrieve diagnostic trouble code(s)...

Hi there - I'believe that's a 1-hr job (with the right lifts, tools, etc.). Any project always takes 3 times as long in my own home garage. Unfortunately, this is not a service YourMechanic offers at this time. Thanks for...

The rough idle may be caused by a variety of things, but this happens most commonly when the mass air flow sensor or the idle air control module have failed. The mass air flow sensor is responsible for monitoring the...

Hi there. Are you getting battery voltage at the fuel pump? Double check the fuses with a digital volt/ohm meter and measure voltage on both sides of fuse to verify continuity. Your fuel pump circuit should have a relay or...

It could be as simple as having picked something up in the tread of the tire. It's surprising how much noise you can get from something like a bottle cap stuck in the tread. A good place to start is...

Your presumption sounds exactly right to me. The only time that coolant enters the passenger compartment is through the heater core. If you have coolant leaking into your interior it is under no uncertainty that your heater core is leaking....

The engine should bolt up to the transmission, but the 4t45e has a lower torque rating than a 4t65e so pushing more power through it might cause problems. There may also be a few subtle issues with mounting the new...

Hello. If the horn is working normally then you have a programming issue. In most cases the control module for the alarm will need to be reprogrammed by the dealer in order to make it operational again. If the horn...

You may find trying to overhaul the motor and swapping over all the parts to the new motor may be the best bet to get the vehicle to run without problems. You do not know what you are getting from...

It is possible that you could be having an issue with your battery or your alternator. I would recommend having this issue inspected by a qualified professional in order to determine if my suspicion is correct. The battery should maintain...

With modern vehicles that have many electronic systems, it is not unusual for parts to quickly fail. In the past, mechanical parts would take awhile to fail and would generally let the users know something was wrong. Electrical parts, while...
