CAR SPEED DROPS REAL FAST AND THEN REGAINS AND DROPS AGAIN.

2002 Jeep Grand Cherokee • 175,000 miles

At 60 mph and rpms @2700 car speed drops real quick like it wants to stop for a real quick second and speed and rpms go back up until reaching 60 mph or 2700 rpms then tries to stop again and cycle repeats untill I bring the car speed to about 58 mph or close to 2500 rpms.
Is it the engine or transmission problem?

Is the check engine light on?

Could be trans, low fuel pressure or cat converter issue.

You need someone to road test it for you to confirm
