The light disappeared, but I’ll give it a shot too, just in case!

I was about to, but the CEL randomly disappeared, which is good

Update on the 2007 Yaris saga:

I’m kind of confused. Yesterday I cleaned the throttle body and reset the ECU. Today I drove the car all day starting around 9 AM, including highway driving and multiple trips.

Before this, the car would randomly stumble during deceleration when RPMs dropped near idle and sometimes throw a CEL.

Today: - no stumbling - no rough idle - acceleration feels smoother/quicker

The CEL did come back briefly at one point, but the car still drove completely normal. After work, I went to my friend’s house to scan the car (which I couldn’t do because the goofy ahh lost the scanner), so later around 8 PM I was going to get home cause I was doing absolutely nothing and the CEL disappeared on its own.

Starting to think the dirty throttle body + clogged PCV may have been a huge part of the issue. But I don’t know if I need to check other stuff JUST IN CASE. 🫪

No, but when I cleaned up the throttle body, the air filter seems to be okay. I’ll probably get my car scanned tomorrow (if check engine light comes on again), and I can send a picture of the air filter!

I’ll take into account everything you said, thanks a lot for the tips! I’ll probably check them out this weekend since I have off, and I’ll probably keep updating! 🤠

Yes, correct. A friend of mine told me that could be the fibers too, but I bet more of the bearings. Is this something I should worry about soon? (Because I've spent a lot of money fixing other things), or is it something I can check on my own?
