Let me know if there is a better place to post this. New-ish to posting on forums.
I have a similar issue with my ka dual cam. I bought the car about 2 months ago, no major issues besides idle drops down to ~400 when clutch pressed and coming to a stop, idle picks back up after completing stopping for 5-8 sec. It use to stall when coming to a stop but hasn't after I cleaned the iacv. Engine was supposedly rebuilt from previous owner. Compression tested and 160 on all cylinders dry, 170 on all cylinders wet. I changed plugs and filters when I bought it, also went through and replaced all vacuum lines. Does have the egr but it seems to be working, have thought about removing it all together.
No idle issue on cold start, only happens when I'm coming to a stop. I still need to check the throttle body but I'm just wondering if guys had any ideas/suggestions.
