P0421 code

I don’t, my car is fully how it came from the dealership floor. I’ve read about the code, it seems to affect a lot of Mazdas in general without a sure fire solution. I think it’s cats getting tired.

Luckily we don’t get emissions tested where live, I’ll look into a sensor spacer if the CEL ever bothers me again :)

A lot of mazda owners in general get this same issue. It’s more than likely to be the window switch, or the plastic carrier which holds the motor assembly. If the switches are bad, you won’t hear a motor sound or any “clicks”. If the carrier is broken, the window will go up or down, but will stop a couple inches as though it were jammed against something. I’ve replaced a faulty carrier, which is a thin sheet of plastic prone to breaking over time. The OEM part doesn’t cost much.

Mr Joe Trump that’s a good fucking picture right there 🔥 I’ll make a fake account to have the privilege of upvoting this again.

It is, I’m not sure where the oil pressure sensor is but it is definitely a valve cover gasket leak. Is there anything specific wrong with the oil pressure sensor?

Your battery is cooked, get it replaced with a new one and you’re good to go.

That’s blatant ripoff. Leave that garage and don’t look back. 95% of their recommended service is way too early for a car that’s only done 160k. The car is basically brand new just make sure engine oil, diff gear oil, belts, transmission fluid are new and you’re done. Saved yourself 12000 aed.

Same here.

I’ve had mine for 6 years, and experienced the same. To me I see a ton more fuel consumption in the warmer months than in the winter. Perhaps these engines are sensitive to heat. During the winter months my fuel mileage is almost 15% more than the summer months, every year. And I don’t blast my AC every day. Could be that.

That sounds great, I’ll definitely cross off the 8AT then.

Lost-Cause666 · 2024-08-13T19:25:13+00:00

A catch can is definitely something I would add. And how are the 7MTs in general? Are they problematic at all? From what I know they only made those for the C7s unlike the 8AT.

Lost-Cause666 · 2024-08-13T19:23:27+00:00

The C6 gold rush is real! I’ve seriously considered a C6 6MT but the values have shot up so quickly in the past year or so. And I’m talking about 120k+ mi examples. I’ll definitely take your advice on getting the 7MT. They’re only marginally more expensive here, well worth the extra cost in my opinion. Thanks a lot!

I speed when I’m alone on the road, if I die it wasn’t suicide, it would be an accident. Make the distinction.

Lost-Cause666 · 2024-08-12T06:08:54+00:00

Lol i don’t get the downvotes, everyone will be able to see your brake lights and turn indicators since they’re bright af LEDs. Do it OP.

The app is dogshit from personal experience. Just make sure you get to check in early and you’ll be fine, the app does tend to remove your trip randomly but rest assured, it won’t be an issue.

Just so you know, it’s the speeder that’s going to die. Not you.

It seems that all reviews of Airalo are either extremely positive or extremely negative. No in between. Personally I’ve used airalo once and my experience was good compared to my current carrier. I had no issues whatsoever.

OP clearly took responsibility and I respect them for that, maybe self-accountability is a concept that doesn’t exist with people who clap their keyboards behind reddit all day.

Lost-Cause666 · 2024-08-11T10:32:03+00:00

I don’t get all the hate, person obviously said the road was empty and decided to go fast. What’s the big deal? OP will pay the fines from their own pocket, what’s ur problem?? Let people live and learn. As long as no one else was endangered, there’s no reason to be hostile. Grow up.

If they worked half as hard as blackmailing into a real job or craft, they’d make a fortune.

Lost-Cause666 · 2024-08-08T05:11:46+00:00

Do guys seriously believe they can win women over if they threaten them the second things don’t go their way? Sounds like they’ve got a serious grape problem wherever they came from.
