The most likely causes are either a parasitic drain on the battery or a faulty alternator. The battery is basically just a storage device which must be constantly charged by the alternator. A battery that is partially discharged often will...
Knowing what code is being stored and causing the Check Engine Light to come on will greatly help with diagnostics. I would ask for help from one of the mechanics at YourMechanic to come to you with a scan tool,...
You should inspect the rear driveshaft U-joints to see if the joints are bad. You may see where the joints are loose or rust around joints. You will need to replace the U-joints if they are loose or making noise....
GM has several technical bulletins that refer to contamination/clogging of fuel injectors for various factors, mostly due to fuel quality and various grades of fuels sold domestically. Now before performing a random cleaning of the injectors, the error codes should...
Hey there. The symbol you are describing is for a problem in the transmission. The transmission can have several issues such as slipping problems, hard shifting, stuck gears, or internal damage. If you need a diagnosis of the warning light,...
Hello, thank you for writing in. If you know that the brake bulbs, relay, and switch are good then you have an issue with the wiring or the ground connection. The body control module also plays a role in how...
The OEM spark plugs are claimed (by Lexus, in the maintenance schedule) to be good for 120,000 miles. However, there are many other maintenance items on this vehicle that have much shorter maintenance intervals such as replacement of the brake...
These sound like the symptoms of an alternator failure. The alternator can cause all sorts of weird electrical symptoms if it has gone bad. While the battery is responsible for starting the vehicle, the alternator's job is to charge the...
Hello. Most of the indicators that the oil needs to be changed are not visible to the naked eye. Simply getting oil hot while driving down the highway will darken it. The road grit and engine wear "debris" is often...
Hi there. You can change the auto locking hubs to manual locking hubs as long as the parts will fit. Just keep in mind, by replacing the auto hubs with manual hubs, you will have to get out of the...
Well the first thing I would check is to see if the alternator is working. I would suspect it would be in the distributor. Ignition module, tdc sensor. A few voltage tests can tell you for sure. I would recommend...
Oil pump failure can happen on high mileage vehicles. This is normal due to engine wear and oil pump wear. Before replacing the oil pump, I would suggest having it properly inspected. A qualified mechanic can perform an oil pressure...
Hi there. Without being there to inspect your Nissan or knowing what replacement parts you used, it's difficult to pinpoint this issue remotely. You might want to verify that all replacement parts are OEM or compatible to your 720 first....
The oil pressure light will usually come on when a few things could be happening. Either the motor is in fact low on oil, the oil pump could be failing or not pumping oil sufficiently or the oil pressure sending...
If you are needing to replace the ignition lock cylinder where you put your key in to start the car, then yes a new key is typically provided with the lock cylinder. Sometimes programming of the key is necessary for...
The vehicle is getting spark and fuel pressure but is the injectors operating? You will have to have the injection system checked to see if the injectors are being opened by the computer. I have seen these cars get spark...
You can get a precise estimate by inputting your vehicle data into the "Get a Quote" panel at YourMechanic's power steering rack and pinion service page. Broadly, though, to give you an idea of the cost, if you do not...
Hi there. They are correct that some of these parts may cause the issue. If the Check Engine Light is coming on, then I would typically scan the computer for codes first. This can give me a good indication of...
I'm curious why you would want to do this and because of the potential liability with something like this. I'm going to say your on your own with such a project. When ever we decide we want to modify our...
First you will need to test compression on all 4 cylinders with all of the spark plugs out and the ignition system disabled. If the compression is good on all of the cylinders, then the valves in cylinder 2 are...
A possible cause of this issue could be a warped brake rotor or a loose suspension part such as a control arm bushing. If your brake rotors are warped and the brakes are applied, this can send pulsation to your...
Hi There, This may be a sign of a faulty MAP sensor. The Manifold Absolute Pressure (MAP) sensor senses engine load and generates a signal that is proportional to the amount of vacuum in the intake manifold. When you are...
The variable valve timing solenoid is mounted in the front of valve cover near the front of each valve cover near timing chain location in front of the motor.
There could be quite a few things that can cause this. Reading out faults from the engine computer will be key to guiding the diagnosis in the right direction. Depending on when the stalling occurs -- at idle, part load,...
Hello, this could be a simple problem to fix. If the fuse is blown it will cause the radio to have no power. You could also just have a bad radio, and if this is the case, the radio unit...
