Hi
I have 93 civic ex coupe. d16z6 automatic
I been having idling problem.
Right now... my idle goes high and low...when it's on neutral or parked.
and also when my car is on drive...and when i brake fully on red light. my car idles high and low so it jerks
when i put my heater on when it's idling on drive, it stops idling high and low.
I've cleaned my intake and throttle body.
and i've turned the idle bypass screw.
i believe i have vacuum leak, maybe the hoses.
Many people told me that it can be the sensor.
Can you guys help me out?

 

u might be low on antifreeze

 

i've put coolant not too long ago. i am wondering if i have to replace some of the hoses. my idle bypass screw is almost shut.

 

then u have an air pocket in the cooling system cuz i had the same problem w my eg8

 

so what should i do? i don't have to bleed the radiator right?

 

i was told that i should clean the FICV.

 

Its IACV, heres the link on how to clean it.

k thanks. is there any link for how to clean FICV? that would be helpful also. thank you

 

You mean FITV? Then here http://www.team-integra.net/forum/di...g+Common+Topic

 

FITV i can clean it with carb cleaner also rite? thank you for the link though

 

Ok i found the problem.
i was told that when your car engine is on and if you block the left bottom hole in tb, and high and low idle stops then the problem is FITV correct?
So the Cleanin the FITV should fix the problem rite?
And um what happens if you block that left bottom hole in tb like...with a cork or something.
thank you

 

Ill bump this bc ive personally never messed with my FITV system so I really dont know anything about it.

 

i parted the FITV kind of. couldn't take the coolant hose. it seemed clean to me. but ya idle does stop when i block the left bottom hole in throttle body

 

new update: i drove after putting it back together. i think my coolant hose that's connected to FITV is loose. smells like coolant burning. and temperature started to go up.

 

i have the same problem i have a 93 civic d15 and recently swap the tranny for a 5 spd... i recently cleaned the throtle body and the fitv and the iacv and the car starts at 800 rpm or so and than it starts to idle up and down again my idle screw is almost shut and when i try to drive off it stalls and shuts off any ideas what it could be wrong? please help ill hate to have to buy another car
