Everything was fine then I started it up and its chugging. A big miss. When I rev the engine it goes away. Other than than that when I idle it it misses. I CAN drive it but I dont go fast. And I dont go far.

Ive been told a couple things. Its either a 02 sensor. (but i dont smell rotten eggs)
spark plugs
or vacum hose leak?

Help is an understatement.
