I have a 91 crx dx with a 94 B18b1 wired obd-1 with a skunk2 mani. well i have had my car running for a while now and it runs pretty good with only one problem that i dont know what to do with. Whenever im driving normal my idle stays cool but then after i get on it, like when im racing whenever i come to a stop my car starts idleing all crazy it goes from 1000k to like 2500k some times 3000, i thought it was a vaccum line leek but we capped everything off, and we've switched the vaccum lines around so many times. I just want to know, if yall know whats going on. I kinda think its one of my sensors but i dont know. help would be greatly appreciated. thanks

if it only happen after u going FAST.
make sure you cold idle valve is functioning normally. (make sure the coolent hose is connected) if it is not, whenever u are flooring it the valve cools down enough and idle takes a ----.

other than that check you thottle cable make sure it is not blinding, it happened to me once that, whenever i am driving really hard/engine heats up, the TB cable blinds and idle goes ----.

hope it helps

 

also check the IACV (idle air control valve) might be clogged up, just take it off and spray it with some brake cleaner.
