The car starts sure enough... after you pump the gas two times before you turn the keys in the ignition. It may be because it is incredibly cold that it start so roughly but i have no idea.. i know nothing about cars. Well okay we get it to start but the engine just shakes the entire car like no other... it vibrates very intensely.. my dad replaced a couple of spark plugs but that did nothing.. i don't know whats wrong....

the car misses when you start it it chugs and whe you floor it just bogs dead you have to barely give it any gas then when it gets going it misses off and on can someone please help me out with this i put good gas plugs filters pvc carb clean mass air meter and every thing i could think of still misses warm or cold
