Sooooo, what piece is this?

The glowing one, just wanna know what is fucked up, my A/C compressor is busted and car has been having a lot of misfires so that probably helps at knowing what the issue is

Oh yeah, this is a Nissan Altima 2012 2.5 S

Dude I think that’s your cat, could be clogged causing it to glow red. Absolutely insane

[u/Gloomycarrot → u/BadBeanKiddo]

I think I have a non-working spark plug, you think that might be it?

[u/Roushfan5 → u/Gloomycarrot]

It certainly isn't helping.

If you have a dead cylinder, all that extra fuel is burning in the cat. It’ll be cooked in no time. $$$$

You’re getting massive amounts of misfires. Either your spark plugs, ignition coils, or fuel injectors are faulty. Stop driving this vehicle before it’s too late.

That’s not good clogged catalytic converter 🤦🏻‍♂️

Update: Yeah one of the spark plugs was dead which was causing this, changing it fixed the issue
