1991 2.2 accord idle issue
Well; I parked it one day and then it ran badly the next. It seems to idle horribly; especially when one puts it into gear. in park or neutral; not so bad. It also seems to have a-lot of power once it gets going 25 mph or more. It has yet to stall, but it idles horribly low in gear and the exhaust sounds like a lawnmower and smells real rich in fuel. any ideas. EGR? IACV?

Thanks. Yeah.it seems to have a bad idle no matter what. so you think the IACV. I took it off and cleaned it and it seemed to do nothing for it. Is there a way to check this to be sure it's bad. Th e part runs 250-350, so it would be nice to be sure. I read somewhere that one can read it and if it has less than 12-14 ohms, its bad. Any confirmation on this.

acmech52. any idea where i could find those ohms numbers? also; when you say valve adjustment. is that a cause from adjusting them or a lack of adjusting them. if it's a lacking, how often should one do that and is there a link on how to that, that you recommend? thanks everyone so far.

only experience i have is from my 07 Fit had 130k+ and the idle when cold was low and erratic. after valve adjustment it was perfect. lack of adjustment. service manual may have all the numbers needed. I don't have a manual for your year car. sorry.

running rich sounds like a bad oxygen sensor. did you check for fault codes just because the check engine light is not always on doesn't mean it doesn't have fault codes stored. also a dirty oxygen sensor wont trip a fault code only when it fails completely.

I just changed the oxygen sensor. and the codes called it out as bad. but after replacing it, it still acted the same. it sounds like a lawnmower until I get it to about 30 mph. then it sounds like all the cylinders are firing fine and in sync.

Well; what seems more likely. The EGR or IACV. I will describe it again. When I start it up it idles somewhat ok, until I put it into gear and then it boggs down to a barely running idle and sounds like a go-cart. However; if I drive it and get it u to speed, around 30 mph, it seems to run great and has lots of power. It has never stalled on me, but smells super rich while running. I have changed the PCV and cleaned both the EGR and the IACV. There is a-lot of oil on my spark plug wires and it seems as if the o-rings may be bad beneath the rocker arms and the valve cover. Could that oil issue create the bad idle I'm having???
