my car has been running real rich for the past few months...enough to turn the spark plugs black in a matter of weeks. about a month ago i got autozone to plug into my ecu and i showed codes for the map sensor, iacv, and a misfire on cylinder 4. the isfire was due to spark plugs and i replaced the map sensor a few days ago hoping that would fix it. the only problem left it the iacv. my idle has been fluctuating for some time between 1k n 2k rpms. i thought i fixed it by cleaning it out but the problem came back. could my bad iacv be causing me to run rich?

 

bump. i really need an answer...

 

morning bump...

 

Setup please?
More details

 

YES I HAD TO REPLACE MINE LIKE 2 MONTHS AGO. YOU HAVE WEIRED IDLE AND SHITTY GAS MILEAGE RIGHT? YOU NEED TO GET A NEW IACV. IT IS LIKE 120 FOR A NEW ONE (ATLEAST FOR A B16A2)

 

its a d16y8...stock. i really dont want to have to replace the damn thing. i was thinking throttle body cleaner and wd40. good idea?

 

If your iacv is throwing a code then I dont think there is a way around fixing it without buying a new one. Unless it was really clogged but you already said you cleaned it.

 

yea it is throwing a code...i just plugged it in today. it came up with the same code twice, at least thats what the guy at autozone said. when i clean it it does get better for about a day, maybe i should clean deeper...

 

Usually you can't just clean and throw back on the IACV like you can the FITV.

Just replace it.

 

damn. guess ill order one from honda tomorrow for 130...autozone wants 160

 

Why dont you buy one off some one on the board for wayy cheaper?

 

i'd think it would be better to get one brand new dont you?

 

Depends..you can can get one for cheap with nothing wrong with it. Or i guess you could get a brand new one if you really wanted.
