I didn't take off the intake manifold.
I want to go over everything myself when I get it back.

There's multiple places you can get a vacuum leak without removing the manifold.

The symptoms you're getting are strongly indicative of either

A: A sensor failure somewhere in the closed-loop system.
- MAF sensor
- Primary O2 Sensor
- MAP sensor (unlikely)

B: Vacuum Leak

C: Horrific exhaust leak at the header/head interface...very unlikely. You'd hear/smell/see it immediately. And you'd probably catch something on fire eventually hahaha.

I'm not jumping to throttle bodies' replacement as quickly as nissan. i mean MAYBE an exhaust leak somewhere considering I maxed out my coilovers.. i could have hit the exhaust but I don't hear anything high pitch when I get on it.

we shall see. still haven't gotten a call to pick her up.

MAP? is it the sensor by the right throttle body?
