i aleady replaced distributor cap and rotor, got ngk ignition wires, and just used seafoam on my car... why does it virbate so much when it idles??? its not the mounts, could it be thats something is clogged? FITV? or the one of the breather hoses?

 

Clean/new air filter?

EGR?

Buy cheap gas somewhere new? Let car sit with almost empty gas tank for an extended while? (Maybe has water condensation?)

Ignition coil?

Proper oil level?

 

havnt checked my egr yet, everything else checks fine. i used seafoam hoping it will cure it, i dont think i did it right tho.

 

Is there a wrong way to do it?
