Low Idle, Sometimes Stalls
98 Civic d16y7.
Just finally figured out why my car wouldn't start, and now that I got it starting again, it's idling really low/choppy. Could this be a clogged PCV valve? Or maybe a failing IACV? The air filter is clean and it accelerates normally. The tach will rest at about 150rpms (yes, one hundred and fifty) when coming to a stop, then it will bump itself up to about 500 and smooth out. Sometimes it stalls, sometimes it doesn't. When it does stall, it fires right back up, and idles normally, until I blip the throttle and then it starts getting lumpy again. Any ideas? Also, how would I get the ECM? ECU? to re-learn the idle? Thanks |

lol yeah i am wondering the same thing, mine does it too but i always figured it was from my huge injectors that i really don't need

Mine does that too. It's wierd because if I turn the AC on it will idle fine. I hope you figure it out because alot of people I know have this very same problem.

Re: Low Idle, Sometimes Stalls
Try cleaning the IACV. Any CEL codes? How old are the plugs, wires, cap, and rotor?

Re: Low Idle, Sometimes Stalls
i know mine does it when i have the heater on full blast and headlights on sometimes but not all the time. doesnt bug me much because it doesnt do it all the time just once in a blue moon. i dont have any cels either. it only happens when im coming to a stop sometimes. im turbo so i have bigger injectors as well.

Most likely the idle control valve. The Girl friends sol does the same. It needs a good cleaning out!
