Narrative:

As we were taxiing out to the runway for departure the first officer was getting the data ready and starting the takeoff data brief. He noticed that the engine N1 indications for engine one was quite a bit higher than the engine indications for engine 2. He immediately tried to diagnose why this was happening and we noticed that there was no air going through the packs. In the meantime I was taxiing and waiting for the aircraft in front of us to proceed. As they started to proceed forward; we followed and during which time I was trying to decide our next plan of attack and getting ready to see if we could go somewhere to take a look at the situation. During this time the ramp controller told us to hold short at the next spot and contact ground. As we continued toward the spot unknowingly missed the spot we were supposed to hold at and crossed onto the taxiway slightly. I noticed it immediately and put on the brakes and called ground who gave us taxi instructions to the runway. In the meantime the first officer did recycle the pack switches and that solved the issue; so we continued with no further problems.first this was our first trip flown in 2 1/2 months since ZZZ reopened its base. Second we were operating in an airport that was unfamiliar to us. The next time I will let ramp/ground know we need to go somewhere and deal with the issue.
