The only way to rule out the battery as a cause, or contributing factor, is to perform a load test (https://www.yourmechanic.com/services/battery-is-dead-inspection) on the battery. If a battery has internal defects, even if fully "charged" it may not be able to...
The speed must be taken into consideration, in order to properly diagnose a shaky steering wheel during driving. A shaking or vibrating wheel at low speed may point to a problem with tires, or with bent/broken suspension components. On the...
The crankshaft sensor is on the front of engine below and behind the crankshaft pulley. The air gap on the new sensor should be set to .020 to .060. If gap is too big it will not start and if...
The problem sounds like the filter is getting clogged or the front main transmission pump is getting weak and internal seals are leaking. I would suggest having the filter screen cleaned and fluid replaced to see if shifting improves? If...
Do you have any transmission fluid leaks or clutch hydraulic control leaks? If the transmission gear oil has leaked out, that can cause hard shifting. If no leaks are apparent, there are only two possible causes of what you describe:...
Hi Omar. Thanks for contacting us today. Shaking with the a/c on can be caused by a number of reasons. The a/c compressor puts a lot of strain on the engine because the compressor is similar to being a small...
If you are referring to the electrical solenoid within the injector, like any electrical part it can fail due to degradation of the insulation, wire breaks and so forth. The injector can be tested while still on the car and...
Code P0400 (https://www.yourmechanic.com/article/p0400-obd-ii-trouble-code-exhaust-gas-recirculation-flow-malfunction-by-jay-safford) does not necessarily mean that there is something wrong with the EGR valve itself. The only way to condemn the EGR valve is to directly test it. In particular Code P0400 includes a circumstance where the EGR...
You may have a problem with the mass air flow sensor causing the engine to run too lean and will cause a hesitation or surge when accelerating from a stop. You may have to have the computer system checked to...
Hi there. I'm not quite sure as to what you're asking, but if your master cylinder (brakes) is low on brake fluid (https://www.yourmechanic.com/services/brake-master-cylinder-replacement), it's possible that you have a brake leak somewhere that should be located and repaired as soon...
Hello. From what you describe it would appear that your vehicle may be experiencing some sort of issues with the transmission or clutch. If it is a manual transmission and appears to be having trouble staying in gear, or transferring...
There are several possible problems that can cause your car to overheat. It could have a failed water pump, which would cause it to not circulate coolant through the radiator, allowing it to overheat. You could have a thermostat that...
A high idle can be caused by a defective sensor or an engine vacuum leak. Have computer tested for codes and engine checked for vacuum leaks at PCV valve or other vacuum hoses and at intake manifold.
What you are describing sounds like a dirty or failing idle air control valve. The idle air control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement) monitors the air intake as it is mixed with fuel prior to being injected into the engine at low speeds...
That is excessive oil consumption. But at that rate, it might be something you can live with. Turbocharged engines will tend to use more oil than conventional engines. But there are a few things you want to look out for....
The time required varies by vehicle year, make, and model. The required time could range from 1/2 hour to literally hours in some unusual designs. For your particular year, make and model, that is a 2002 Protege, it requires about...
Hi There, Unfortunately, it sounds like your motor may have gotten hot and resulted in some kind of damage that caused it to lose oil pressure, which may have made the problem worse. As you know, there are generally two...
Hi there. With the information given, it sounds like you accidentally put 3 bottles of Gas Heet (water / antifreeze remover) into the gas tank. There is to be only 1 bottle of Gas Heet to a full fuel tank...
Hello - a knocking noise while rolling in neutral is likely a damaged Constant Velocity joint (https://www.yourmechanic.com/article/is-it-safe-to-drive-with-a-damaged-cv-joint) or a wheel bearing with a "hard spot" or damaged position in the bearing. Acceleration puts additional load on the CV joints, so...
There is no way for me to know if you have bad piston rings based on your statement. I would recommend that if you already have the head off for repair to the valves then it is now the best...
