Common Points for Vacuum Leak 2007 Tacoma V6

Would someone show me common points where I can spray brake cleaner to detect vacuum leak please? If you have pictures that will be better, thank you. It’s 2007 Tacoma V6

 

There's not really many places it can leak, just a few hoses and the upper intake gaskets.

Why do you suspect a vacuum leak?

 

I notice that when park in the parking lot and my engine idling around 600~ RPM. While idling, I usually feel vibration when sitting in driver seat and this happens constantly which irritate me.

What I’ve done so far to diagnose the problem:
- Changed spark plugs
- Cleaned throttle body, but problem still persist so I replaced it with an OEM.

So as of right now, the problem still persist.

 

2.7L or 4.0L engine?

If it's the 2.7 those vibrate a bit more at idle than the 4.0.

If you have a scan tool look at fuel trims, if they are +/-10% at idle you most likely don't have a vacuum leak.

 

It’s 4.0L V6, I have the BlueDriver scan tool, will absolutely try that.
