Q: Oxygen sensor problem

You may have a warped rotor (https://www.yourmechanic.com/article/is-it-safe-to-drive-with-warped-rotors), this can be checked with a dial indicator to measure the runout of the suspecting rotor. If the rotor is okay then you may have an ABS problem with the wheel sensor causing...

Automatic transmissions can be tricky. Luckily, as odd as it seems, the fact your vehicle is setting a warning light is a good thing. This allow you to run a diagnostic scan for trouble codes, and will help narrow down...

This may not be very hard to solve. Code P2177 (https://www.yourmechanic.com/article/p2177-obd-ii-trouble-code-system-too-lean-off-idle-bank-1-by-spencer-clayton) means your engine is running too lean. The most common cause of this is an air leak in the intake system. Since you've just been working under the hood,...

Hi there. Check the crankshaft position sensor and see if there is power to the sensor. If there is power to the sensor, then put leads from a digital meter on the sensor and crank the engine over. Check to...

Well I'm not sure about the mechanic's use of terms. If the oil pan is "sweating" oil, then that would dictate that the oil pan is already porous. It's not an everyday thing to happen but I have seen it...

Hi There, The lack of oil certainly can contribute to the tapping noise you hear which is likely metal on metal in the valve train area creating this sound. I would suggest having an expert from YourMechanic come to your...

The engine is very common to have an intermittent cam or crankshaft sensor. You can have the computer scanned for codes to one of the sensors and replace them as codes are stored. If you have codes for both then...

Hi there. Typically an engine tapping noise (https://www.yourmechanic.com/services/car-is-making-a-noise-inspection) is caused by either cylinder head lifters that are loose or worn out, rockers and valves not properly adjusted, a timing belt or timing chain that is loose or crankshaft / cam...

What you are describing is often a sign of low transmission fluid (https://www.yourmechanic.com/services/transmission-fluid-service) or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car's...
