*COLD START PROBLEM*
Welcome to my first post.
The story goes that I got my EP3 and didn't use it right away so when I came to use it after a couple of weeks the idle was hunting even when warm between 1.5-2.5k rpm. Gave the car a rag and it cleared itself simple.
Recently I just done a clutch change which means unplugging sensors etc which may disrupt it. The car was off the road for winter so wasn't started or driven for weeks. When the clutch change was done it was started and done the same idle hunting problem. Gave the car a rag and but nothing changed. I used the car for 3 days on the road still giving it a boot and still nothing.
I read online to clean the ivac and the throttle body so I removed the throttle body and the ivac and cleaned everything, all the sensors aswell. Back together, gave it some and still no change. On further investigation the sensor that goes into the air filter (Tegiwa induction kit) was split as in the wire casing because it was rubbing on the battery. I put some electrical tape on went a drive and the idle hunting got slower, and eventually dropped to a good 850-900rpm idle.
However when I now start the car cold as in for work in the morning or after work when it's not been started in over 5 hours it hunts on cold start for 5-10 seconds then sorts its self and continues like normal or I have to give it a rev for it to clear itself.
Any ideas? Sorry for the bible of a story but just want to make it clear the factual issues. Personally I think I need to change that air filter sensor or possible an O2 sensor. Engine management on due to decat pipe. Car drivers perfectly fine and hits vtec with no issues, thanks in advance.
