im experiencing erratic idle in my 98 civic lx - the idle just goes up and down once the car heats up. i have been checking around and the general consensus is that the iacv is the issue. where is the iacv located? and could this actually be the issue? PLEASE HELP !!! i have a trip from fl to ny planned inthe next week and i would appreciate the help on this.

what trim

 

if its an lx i beleive its the white looking deal underneath the throttle body, i have a buddy who has a 96 lx and his iacv is located underneath the t.b.

i believe its #2

 

It is #2 in this diagram.

 

If it's continuously going up and down, it sounds more like a vacuum leak to me.

 

probably an air bubble or low coolant

 

thanks for the help guys.....i took the valve out and cleaned it and now the car is ruinning quite nnnnnnniiiiiiiiiicccccceeeeeeeeeeee

sometimes that works, but other times youll just have to replace the iacv, thats what i had to do in my case, i cleaned it but it didnt help so i bought a new one....but im glad you got it worked out...
