was on it real hard coming home from school and i heard a nice pop noise and now my vacuum is ALL over the place like no tomorrow,everytime the engine is revved it wants to die and makes a popping noise ALOT,checked my plugs and 1 and 2 are really rich(nice and black) and 3 and 4 are super lean( white and red) cant get any rpm's out of the engine either i dont notice any smoke or anything and antifreeze is all there still no weird smells,ill compression test tomorrow
