its normal to a degree to expend more engine power while running the a/c...you may need a tune up

When you ask a question about a car, it would be better if you could add the inforamtion about your car. I would judge that it is a 4 cylinder small car.
In any case, your engine is not running properly.
Only a specific set of tests can determine the exact cause, but as cars get older, the timing Belt/chain
stretches and slows down the Ignition timing. I would have that checked first. then the Plugs.
Also make sure you are using the right gasoline for your car. some cars require higher octane and some require lower octane. Manufacturers usually recommend the right type as listen in the owners manual. 90 percent of all Engine trouble will be Ignition.
Settle that item first.

Depending on age of the vehicle and AC system you will get a little vibration or known as Engine RPM decrease. This is due ot the load that the AC system pulls of the engine while in use.
Missing can be just that the AC system is pulling such a load of the vehicle that its making it run at lower RPM and seem to be missing. Id have the car looked into by a repair facility to make sure that the AC system is working correctly. The computer / or if vehicle is older it uses what is known as a STEP up solinoid that causes the Engine to run at higher RPM for that extra demand of power at the request of AC. If the vehciel is newer it uses other variables to step up the Engine RPM for that extra load.
Good Luck.

A slight vaccuum leak is possible. Try turning the A/C on while idleing and then turning the steering wheel, to see if the vibration worsens, if so...... a vaccuum leak is still only a possibility. More than likely, you have a sensor problem.
Does it seem to hunt? Go up and down in rpm's- that is more than likely the idle-air control. Again, hard to determine without proper diagnostics.

The real culprit is not the engine. You need to service your car's A/c as early as possible. Periodic maintenance of A/c is compulsory for all cars.

Sounds like it has a miss. Find out which cylinder is missing. Check the spark plug. If it looks dry, there's a fuel problem. Possibly a bad plug wire. Hard to tell without more info. Good luck.

Probably it is due to running AC on high speed with less vehicle speed. Try to run the AC on high speed when the vehicle gains momentum
