You can't ask your dealer to smell your air filter?

I could.. But I just don’t have time for this right now.

Chasing tails sucks... and definitely not normal what is happening to you.
Lots of comments here, but maybe as someone said : high pressure fuel rail?
EVAP seems to be out of the question. maybe?

The Hybrid 4runners have a collection of "chirps" & "whirls" going on.
- electric parking brake.
- Hydraulic brake pressure pump (when you fist open driver door )
- the EVAP "thing" when it sits parked for a while ( mine is a loud Chirp a second long.)

Do you have another dealer option you can call and hopefully get better service?
This "bye bye" we can't figure it out answer is BS for your time wasted already.

Good luck and keep us posted.

Yes there are plenty of dealerships I can take it to but that's a last resort as I want Toyota to tell me what to do versus me guessing where to take it and hoping I get better service somewhere else.

Test the closed garage:

1. Portable combustible gas detector (best method)

• Often called an LEL detector or VOC/gas sniffer
• Used by mechanics, firefighters, and HVAC techs
• Detects gasoline vapors (and other flammables) in ppm or % of LEL
• Battery powered and spark-safe

This is the correct way if you want certainty.

Thank you! I will definitely look into this!

How does "smoke machine" work to detect fuel leak?

Has Toyota completed a "smoke machine" test? Usually that's what I would do when I'd have a vehicle come in with an issue that was fuel and evap related that was harder to visibly see.
