    how easy is it to install a new O2 sensor?

    The mechanic I know will do it for $100. I already have the parts. I really hate having to go under my car without a car lift that's why I probably don't even want to try installing it myself.

    Codes PO140 and PO171, what are these telling me?

    The maf sensor is the idle air control valve or not? Where would the IAC valve for my 2015 mazda 3 be located?

    Can I wash what's under the hood?

    I was told yes. It's very dusty. So should I spray an all purpose cleaner (I found one on the automotive isle at Walmart)? Can I then spray water all over what's under the hood? I was told yes since my car is Japanese and its computers are internal. I just worry about the wires and connectors. I...

    Codes PO140 and PO171, what are these telling me?

    Maybe it's time to replace all 4 ignition coils too since it's already 155K miles? I've never replaced it ever.

    Codes PO140 and PO171, what are these telling me?

    I will. I do have the maf cleaning spray that I used for my old car. The car is a 2015 Mazda 3 isport with 156k miles on it. For a newer car I find it strange that the O2 sensors would go bad that quick!

    Codes PO140 and PO171, what are these telling me?

    Each time I'm at a stop, the car sounds and feels like accelerating. A week after, the check engine light came on with those 2 codes. Also, the car would not start at one time but I kept trying to turn it on, and it started finally.

    Are trade-ins ever worth it?

    I owe about $6500 more. It was bought new from the dealership. That's why I thought a trade in might be "ideal"? I guess not?

    Are trade-ins ever worth it?

    My car is a 2015 Mazda 3, over 100,000 miles (do Lyft and Uber). Still owes about $7K. To trade in or not, for a 2018 Mazda3.

    how to install a fog light kit?

    I have a 2015 Mazda 3. I see that when I removed the fog light "panel" it looked like it's easy to install/plug and play, but when I called the dealership they said I need the fog light switch as well. How and where does that go? I see cheaper fog light kits for my car for less at rockauto.com...

    is it possible for me to slightly dim the dashboard lights?

    I read an article that those lights can be distracting during night time driving, so I was just curious if I can dim these dashboard lights by 50%?

    Tinting front windshield?

    I've seen the tint laws but there are tint films that are not noticeable as tint film, say anything higher than 50% looks as clear as day.

    can a product made to be used out of the box be hard wired into the car or not?

    some devices like my dash cam didn't come in a ready-to-hard-wire bundle. My brother's dash cam did which was why it was hard wired with ease for a fee of $75. I think I'll say no to hard wiring for now since I like to be able to take it out and use in another vehicle. My dash cam has a high...

    does your tire pressure sensor go off when hitting a bump?

    what would the TPMS light flashing indicate? By the way, I see you owned a Miata. I saw the 2016s and they look gorgeous!

    Tinting front windshield?

    I've thought of having my windshield tinted up very light only for the UV protection purpose. Could this also lessen the heat going into my car during hot summer days? I ask this because my dash cam is not meant to be left in extreme weather so I'm assuming lessening the effect of direct heat...

    does your tire pressure sensor go off when hitting a bump?

    my setting is usually at 35 psi. My tire max is 40 psi. Oil change service places usually put 32 psi in my tires. Not sure if 32 is sort of like "standard", even the "free air" machines are defaulted to 32 psi.
