ok i cleaned my iacv today to try to fix my idle problem n it kinda worse it idle under 1k. and my car feels like its gonna die when im at a light. i friend told me to do something with my coolant but idk. anyone here have the same problem?or know whats wrong? lmk plz

 

help anyone?

 

man really dont know how to solve the problem but if it makes you feel better all three of my honda's are doing this and i cant figure it out sounds like all of them do it and everone says its the iacv but i tried to clean mine and it didnt help either

 

and mine is idling above 2 grand!! i cant figure mine out either

 

sometimes they are bad and cleaning them wont help. but if its trying to die and idle surges you might want to look for vacuum leaks

 

yeah guys might be a vacuum leak thats what ive been told. ill see if its a vacuum leak

 

help?

 

Your fuel filter may be clogged, sounds like the problem I had on my old civic.

 

I'm assuming you took your iac completely out of the car, thus opening up your coolant system right?

You have to bleed the coolant

 

is it just idling low? what vehicle? have you tried to adjust the timing with a timing gun?

if your 0BD1 check the FICV under the throttle body some times you need to take off the back and tighten up the big white disc with a large flat tip screwdriver.
