My 2016 jeep compass makes a loud engine noise when I accelerate At around 65mph the tack registers about 2600 rpm. It seemed to have occured whe I had the fuel injectors cleaned at jiffy lube.

Sounds like a vacuum leak. Check that all your vacuum lines are attached and in good condition.

Do you often run your gas tank to near empty?
If so.......
This sounds like it may be as simple as cleaning the water or gunk out of the gas tank which is what I always do 1st because it's easy and inexpensive.
If your fuel is contaminated with gunk, grime, water and/or bottom junk like rust this will cause stalling and rough riding!
Try spraying a can of starter fluid in the air intake and see if it runs! If it does, it's most likely bad fuel or clogged injectors so....
Fill the tank with High Test, Add some dry gas and a good fuel system cleaner or 2 or 3 and this should dissolve all the gunk and clean the injectors! Read & follow the cans' instruction carefully.
If this cures the problem never let your gas tank get below 1/4 and especially never run it to empty as this is when the gunk and/or water will enter the system!
Hope this helps!
Good Luck!

SOURCE: I have a 95 Isuzu rodeo. The engine makes a loud,

ATTENTION!! Do not run the engine if you do not want to have to buy an engine!! I just solved this problem with my own 95 Rodeo the problem you are having is common on 95 rodeo with 3.2 L engine. Failure of the hydralic timing belt tensioner will allow the tensioner pulley to knock against the top of the tensioner unit ( inside timing cover lower left side of crank pulley little cylinder looking part ) held in by 2 bolts when you take it off if you can depress the button its bad . Dealer has part for $110.00, so go to auto zone but they dont have it listed for 95 rodeo have them look up timing belt tensioner for 95 honda passport $76.95 takes 2 days VDO (Vendor Order only) not a very hard job have fun dont forget to change the timing belt and water pump for good measure after the complete job is done you should not have to worry about it for another 70,000 miles.have a good day

Testimonial: "This was the exact problem with my Rodeo. Thank You so much."

SOURCE: A loud ticking noise?

No I would not chase to the pistons, these vehicle were very comon in creating HLA noise hydraulic lash adjusting valves, meaning the valves pump up with oil as the oil gets thinner they dont pump up as fast and create a very loud ticking noise, I would not express a great concern over simplicity, dodge was famous for this, they really were.
