Hi, so I have an intermittent idle issue.

When coasting to a stop, and clutch in, the RPM's will drop below normal and sometimes stall.

I've done the searches and have gone through most of the troubleshooting in there but haven't had any luck.

The part that's giving me fits is I'll go through some days with no symptoms at all, and other times I'll get it at each stop light

The ECU is not throwing any codes.

So far I've
Cleaned the IACV
Went through each vacuum line
Checked the M/C for leaks
Checked Spark plugs

The next thing I need to check is the fuel filter but is there something that I'm overlooking?

Thanks

 

Throttle cable. Mine does this as well. Have a DOHC ZC in my EF hatch and also the cable will get stuck where it will idle at 1500-2000. All i have to do is blip the throttle and it goes to normal. Hope this helps and is related.

Haven't found a fix for the throttle cable yet, and normally I'd just replace but I'd like to get one that fits so I don't have to do modification. ZC Parts @_@ Pain in the butt.
