4.7L 3rd gear feels sluggish
Jeep feels like it's major down on power when it shifts at WOT into 3rd gear. It feel like it just runs out of breath. I'm at 66k miles and haven't changed the PCV or the EGR yet. Idle seems like it's beginning to dance around so I might swap out the PCV. While I'm there, I'm wondering if maybe the mass airflow sensor might be getting old. My old Tahoe had one going out and it felt like this. I have a K&N intake with a relatively new/clean filter in it. Thoughts?
Also have a superchips flashed but I've already tried flashing stock with no change in performance shifting to 3rd.
