I have a 1998 accord. the idle on it is not good. sometimes it idles back and forth from 1100 to 2100 rpms. i changed the iacv, and the map sensor. there is a lot of suction where the idle air control valve is, in the hole there. should this be, PLEASE HELP? its a 1998 so it doesnt have a fitv valve does it? coolants good, wat else shall i check

 

Any CEL on? Sounds like maby a sensor. Or vaccume leak. And what hole are u talking about?

 

If you have replaced those I would look for a vacuum leak. Check the throttle body, intake manifold, and all the sensors from the intake manifold to the head.

 

its the hole there in the front valve if that tells u anything, what for sensor wud it be?

 

hey thanks a lot live2rice, does it have a fit valve?

 

Get a vaccume gauge with a T fitting and start checkin vaccume hoses and compair with shop manual. I wrapped all my vaccume hoses in electrical tape where they connect to metal hoses because i had provlem with mine blowing off and leaking all the time. Even slight leaks cause problems. But id check them first cause it sucks cutting tape everytime u gotta replace something.

 

hey, jroxz44, u had asked wat cel was on. the iacv sensor was on and the map sensor was on. i changed that,now its telling me the iat sensor is bad, which ithadent earlier. shud ichange this sensor? thanks

 

Have you bled the air out of the coolant system?.

Idle going up and down is a symptom of air in the system.

 

yes, i bled the system that doesnt work, i looked today on top of the air manifold there r three differnet places for hoses, two which have hoses to them, i which doesnt. this is sucking air in, shudnt there be a hose connected there???

 

yes
this should help
