alright... whenever i come to a stop... and the car idols... i can feel a very slight shaking of the car...its not constant... its on for a second then it smothes out... then its shakes... then smothes... can someone tell me what this is? is it a knock?... do i need a tune up? will a tune up fix the problem? thanks

 

a tune-up should help.

 

thats what im thinkin.... i know my wires are good but cap and rotor dunno about... and i def. know the plugs gotta go... i think they havent been changed in 10 years.... honestly... but the car still runs great..... well the car hasnt been really drivin in 10 years either.... AC delco plugs should do the trick.... i just gotta wait till a pack of 8 of them come into work... i only see 4 on the shelf...i might have to look into other stores....
