Hi, I have a 00 civic ex which has been having a very low rpm rate these days when idle. In park it seems to go up a little bit but when I am in gear and at a complete stop it goes down from 500 rpm to as low as 100 rpm. Sometimes it feels like it wants to die but so far it never has. Anyone know what it can possibly be? I have recently got an oil change and replaced the spark plugs and wires. I was thinking maybe a dirty IAVC? Any suggestions would be great. thank you!

 

it wouldn't hurt to clean it, but did you try messing around with the idle screw?

 

i did but it didn't solve the problem. any more suggestions? i am completely stuck on this...

 

bump

 

mine does the same **** but only when its cold out side .. if i start it and it idles really low and if i adjust the idle screw its fine until I turn it off .. then it does it again .. TPS?

 

CLEAN THE THROTTLE BODY!!! carbon buil up ca cause that too!!! and like hawaiianej6 said try the idle air bypass screw.. turn it to the left about 1/2 a turn....
