Hey guys I got the Korax intake, & I'm having a problem. Can someone tell me what's going on? When I'm driving and I coast to a stop with the clutch depressed and the rpm's go down it does'nt stop at idle the engine shuts off. I have to downshift to 2nd and goose it a little to keep the engine running. Can someone explain to me what's happening and what the cause and cure is?
