I've had my Daytona for about three years now and 2 weeks ago mine stalled at a light for the first time. I started looking around the intake and noticed a little oil condensation around the connections of the vacuum hose that connects from the oil fill, to the intake. Pulled the intake off up to the throttle body and noticed some black tar like substance that was blocking air flow at idle, which was obviously oil being sucked into the intake. I've read that your are not supposed to spray any cleaner into the throttle body so I wiped it down the best I could.
Idle was smooth again but couldn't stop thinking of the baked on oil in my intake. I ordered a oil catch can and moes ported throttle body. I couldn't believe it when I took off my throttle body and looked at the back side of it, completely black.
long story short, check your throttle body. At idle it is nearly closed and any substance on the walls will block air flow.
most vehicles have a similar set up. check out oil catch cans, I found a lot of topics on them. I had to get one once I seen my throttle body, and seen how the cans catch the oil before it gets to the intake.
