weird sound when i rev up my engine.

so i been told from two shops that my jeep is running fine but i feel a slight stumble from it at idle. also i get this weird sound from my engine i hear more from the inside than the outside. the only issue is the jeep went into the shop a month after owning it due to needing a new cat. i have already replaced the spark plugs three times. new oil change with castrol syn mobile 1 filter. new aftermarket pcv valve but getting a oem one tomorrow the aftermarket one is really loud with the ticking noise. air filter fram. no check engine light on. i also notice it revs at bout 1200-1400 rpm from cold start for bout 20 secs. but then goes to 1000 rpm for bout 20-30 mins. then after i drive it bout 3 miles or so it will idle at bout 600-650. please if anyone can help me or lives in the ft campbell ky area and can help i would be very thankful. thanks

also i attached the audio file in a zip file cause it doesnt let you post audio files here. thanks
