The first thing to check, always, when you're having a problem with an automatic transmission, is the fluid level and condition. If it's low, top it off, and if it's dirty have it changed. Make sure you check it with the engine running and in park on a level parking spot.

Your engine rocking back and forth means your motor mounts are bad and need to be replaced.

Thank you.
I changed the fuel filter and had a tune up like 7 months ago.
I just got my motor mounts changed and they are working properly. When the car is in park the engine just rocks back and forth. I am still trying to look online what the problem is and a forum said to use fuel injector cleaner so i'll give that a shot tomorrow

Also if it's low, make sure you use the correct fluid type. Your Camry calls for Dexron III fluid. Dexron is backwards compatible so you can also use Dexron VI which is better and some people have smoother shifts with. I've heard good things about the Mobil 1 Dexron VI ATF. If you get the fluid changed, it's also a good idea to change the filter in the transmission since it may be getting clogged and blocking flow.

Did the tune up include spark plugs, wires, and/or coils? It's possible your spark is weak on one cylinder, so it's misfiring. One way to check is to do a cylinder balance test. If it drops less RPM on one of them than the others that cylinder is your problem.

I got my ATF changed like a year ago so I guess it is time to change it.
The tune up included everything from fluids to spark plugs. But i'll check them out. Thanks bro

Check the intake boot between the air box & throttle body for any tears or cracks.
