i am from BG and my accord is eu model 131hp f20z1 engine cc7,2.0is modification.
1994 year so no obd ii connection i dont know what kinda connection have but for sure its not obd ii i can make diagnostic with paper clip and i have engine mil codes but right now i dont have any yellow light so i cant make anything. And my idling problem troubles me a lot!

 

Well I notice 2 things ....... 1 when it loops up and down it normally means u have a vaccume leak somewhere. And when slowly drops really low after reving that seems like your IACV isn't working properly. Did you set your base idle properly? According to the manual? I would try setting that first and go from there. Then if no change after properly doing it I would check for vaccume leaks. If you had head work done recently their could be a leak in your intake manifold or they coulda knocked a vaccume line off or broke a dry rotten brittle line while working.

 

I think you might have hit the answer right there Jroxz44.
Sounds like the answer to me after I looked it up.

 

Check for codes. Not sure what the yellow light is to the right of the tach, seen about five seconds in.

A cleaning of the IAC never hurts. Also be sure all of the air is out of the coolant system.

 

i dont have any error codes.
