Hi guys, Need help and expertise. I have an Civic si 2010 130k miles, bone stock no mods. Well it started a while back; only at a cold start coming to a red light literally down the street. Every thing works fine intel I push the clutch in and rpm needle just drops to zero. Oil and battery light comes on and literally I cant even tell it stalls out intell I try to give it gas. Well I have done my research on the issue but every thing that I see is to clean Throttle body, iac and etc....
Well I found a vacuum leak while back and I fix it. I clean both throttle body and Mass flow sensor (MAF) as well and also I did Idle relearn procedure and nothing change. It idles fine around 750-800 rpm and no surging at all at a stop.
Note this only does it at a cold start after it warm's up I feel like the rpm's is bounding around when I'm coming to stop(clutch engage) but never go's below 1000 rpm's (when slowing down) then 800 rpm's (complete stop).
I have done all the research I can; I came to a road block.
Note again please don't suggest cleaning IACV or TP this civic does not have IACV(electronic throttle body). Also TP is one component with the throttle body on the side. I really don't know if its a good idea to start opening that. lol I have notice oil in one of my vacuum hoses the one connects to valve cover head and air intake duct which the vacuum leak originated.
No cel ether. Here is my video I record as it does it. And i I upload to youtube https://www.youtube.com/watch?v=9xlTd1Wbtm8
