The engine is running rich. Clean or replace the spark plug and the air filter. If problem persists, close (turn clockwise) the needle valve on the carburetor 1/8 turn.
if it's idling rough, I would suggest cleaning the throttle body with carburetor cleaner.

I experienced this problem after my car was leaking motor oil due to old faulty gaskets that needed to be replaced. Apparently because of the oil spreading everywhere it reached the engine mount. The oil combined with the heat from usage caused to wear down the rubber portion of the engine mount. I noticed the rough idling was gone once that piece was changed. Side note: It also helps to make sure your timing belt is well calibrated to determine proper idling. ANSWER: Another posibility is a vacuum leak or an air leak between the MAF meter and the intake plenum.
It depends on how long you are idling, or how fast you are going. If you know you are going to be idling for a long time, it's best just to put your car in park.

Your MAF sensore is either disconnected (the one on top of the intake tube) or you vac lines have become disconnected. The vac line is directly under throttle body.
Erratic idling, surging, and the "up and down breathing" are usually caused by a dirty or clogged air filter.

They can touch down on both flat and rough land.
Running the leaves over with a lawnmower shreds the leaves into smaller pieces which decompose faster. Leaves enrich the soil as they break down and create a better growing environment for plants. If you are using a lawnmower with a bag you can collect the shredded leaves to add to your compost bin.
