A P0125 code says that the engine is not reaching sufficient temperature to go into "closed loop" operation. Closed loop operation is essential for fuel economy and low emissions. Basically it's saying that your engine is not warming up. Replacing...

Hi there. Any time you run the A/C, the car will be reduced in horse power because the A/C runs off of a belt that powers the compressor. If the compressor is failing or was faulty to begin with, this...

Hi there. Unfortunately, without seeing what repairs were made and how the ignition switch was installed, it's hard to give you advice on how to get the steering column unstuck. You might want to have one of our mobile mechanics...

There could be a knock sensor that is sending a false positive signal to the ECM. If a knock sensor detects engine knock it retards the engine timing to try to stop it. If the knock sensors are working good,...

Common causes of engine stalling and rough idle include a faulty mass airflow sensor, faulty engine coolant temperature switch/sensor (typically at cold start only), worn spark plugs, wires or defective ignition coil(s), inadequate fuel delivery or pressure (clogged fuel filter,...

Whenever there are multiple causes of vehicle vibration, which is probably the circumstance you face, it is best to fix the obvious causes first because that will greatly simplify diagnosis and identification of the remaining causes. So, in your circumstance,...

Hello, thank you for writing in. An alternator replacement typically takes around an hour. This is dependent of course on the condition of the old unit and how difficult it is to remove. The tools needed are fairly basic. The...

Hello, thanks for writing in. This sounds like your clutch disc is worn out and not connecting the engine and transmission together when you let out on the clutch. You should not rev your engine to 8000 rpm or you...

This may be related to the transmission being low on fluid or potentially a bad transmission control solenoid (https://www.yourmechanic.com/services/downshift-solenoid-replacement). As you may know, every time a gear change is required, the car's computer activates a transmission solenoid, which directs transmission...

Hello! I suggest having the vehicle inspected by another technician to get a second opinion. Usually when a Check Engine Light is on, the vehicle will have some type of issue. Rarely will a Check Engine Light illuminate when nothing...

A common cause is the brake light switch contacts are either stuck closed or the brake light switch is not properly adjusted. A short circuit in the brake light wiring is also a possibility. If you desire a resolution of...

It is possible that your alternator could be failing. When an alternator fails, it can cause other electroncis on the vehicle to malfunction. I would recommend starting by checking the charge output of the alternator using a digital multimeter. If...

Hi There, Codes P0301, P0302, P0304 relates to misfires in cylinders 1, 2, and 4. Codes P0401 and P0402 relate to the EGR valve (https://www.yourmechanic.com/services/exhaust-gas-recirculation-egr-valve-replacement) not functioning properly. The EGR valve is likely detecting that there is either a condition...

This symptom is the TCC (Torque Converter Clutch) is slipping in and out while driving. To check this condition, scan the computer to see whether the TCC action is being commanded by the computer. There could be a problem with...

Hi there. It's possible that the shifting issue could be related to the clutch, but that seems more like a gear linkage issue. The engine vibration is most likely not related; and could be caused by a damaged vacuum line...

Hello. If your vehicle is no longer going into gear after a clutch service, it may be possible that an issue occurred while the service was being done. Perhaps a problem with the clutch fork, or hydraulic clutch mechanism that...

You may have a dirty or failing idle air control valve. The idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle. Since...

Hi there. As you already know, replacing components without diagnoses can be expensive and time consuming without resolution. A few things come to mind concerning the lack of performance. First, camshaft timing needs to be checked. When the engine is...

Hi there. From the description you have provided, these symptoms need to be properly diagnosed. Replacing parts, without diagnoses, can be expensive and time consuming. Assuming the engine is mechanically sound, the description you provided about the spark plug condition...
