I have a B18B in my 96 Civic EX. Ever so often when i let my car idle.. it will begin to sputter/ bog and my rpms with drop considerably! I replaced my sparks plugs... What can this be? Thanks!!

 

Can it be my fuel filter??

 

try checking for any vac leaks.

 

I have checked for vacuum leaks... can one of the screws not beinhg in on the iat sensor cause a vacuum leak? my car actually idles fine it just every probably minute.. i sputters/bogs then goes back to idleing fine... i cant figure it out..

 

Bump for answers/advice..
