I’m working on a ’96 Jeep Grand Cherokee 4wd AT I6 (L6). It is having performance issues, rough idle and stalling. One of the diagnostic tests I performed was a power balance test. I did this by disconnecting the injectors one at a time. The only anomaly was on cyl #3. When I disconnected #3 the RPM rapidly increased.
I’ve not experienced this result and need help interpreting this.
