What could be some reasons why my motor would be shaking a little! i know that it could be that a cyclinder is missing out! But what could be some other things? Im getting new spark plugs should i get new wires too if i havent changed them since ive had the car and also what kind should i get ????

 

Loose motor mounts?

 

Bad dampener maybe? Did the shaking start all of a sudden? Does it go away/get worse with rpm/speed?

 

its that big cam you installed!.. oh wait. nm

(wishful thinking)

 

Add a fuel injection cleaner to the gas tank, Have a flush done where a cleaner is pulled into the vac line and run through the engine. May be wires/plugs.
