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.
