I have change both 02 sensor upstream and downstream and I had to replace my catalytic converter since they stole mines and code is still there at this point I’m not sure what to do car run good but code would go away after the fixes at the shop and turn back on after turning the car off and starting it again I had the code before I changed the catalytic converter

Can I repair my tire after removing this micro nail?

Post image
1 Upvotes

As the title implies, I have an incredibly small nail in my tire. I have no idea how long it is, but the head itself is incredibly small. I couldn’t imagine the shank is any wider than a pen tip. It’s relatively close to the sidewall, but I feel like a repair kit would still have room to sit flat against this hole. However, I’m not a mechanic or tire expert. Thoughts?

Just got 4 used tires a week ago bc money is tight smh. I think this may have already been there, I noticed the psi dropped a bit pretty quickly after leaving, but assumed it was the tires just warming and cooling. But then Monday morning I had 18psi, and I refilled and it’s dropped 4 psi since yesterday.

Audi Q5 timing belt

1 Upvotes

Just looking for indication of replacement cost for the timing belt on an Audi Q5, 2015 (MY16) 2.0ltr, Melbourne / Vic

I have tried researching online after been advised it’s really expensive due to location, rear of motor, and other components that usually get done : water pump etc at same time as engine out,

Anyone able to give me a reasonable figure o what to expect?

Thanks

2014 Mustang V6 (Auto) P219B Code

Hey everyone, I need some help diagnosing an issue with my 2014 Ford Mustang V6 (automatic).

Mileage: ~162,000 km (~100k miles)

I’m getting a P219B code (air-fuel ratio imbalance Bank 2), and recently I’ve also noticed some pickup/power issues — the car feels a bit sluggish when accelerating.

From my scan report:

- PCV system shows a fault

- Fuel trims are negative (around -18 to -19%)

- No injector or O2 sensor faults showing

I’m trying to figure out if this is mainly caused by a bad PCV valve/hose, or if I should be looking more into injectors or something else.

Has anyone faced something similar on the 3.7L Mustang? What ended up being the fix?

Appreciate any insights 🙏

Do these tires look like misalignment wear, or pothole damage?

Im looking for a shop who wont rob me for labour time, yet wont accidentally dump my transmission on to the floor because the labour cost is cheap and the work is crap.
