Daytona 955i Idling Fault

Alan Campbell · Jul 26, 2020

When approaching a junction my 2000 Daytona 955i does not idle and cuts out, if I keep the revs up I can generally get it to remain running, however if I let the revs fall it will cut out. Any suggestions?

Welcome Alan.
It sounds like a classic case of leaky IACV hoses or throttle body gasket. There’s lots of info around the forum about it so have a search around.
Might I suggest you post a thread in the newbies section introducing yourself too.

I had this problem many moons ago and it was CO levels that needed adjusting. Needs a mechanic with a CO meter they can shove up the pipe really. Followed it up with a TB balance and has been sweet ever since (ie for many years!)

Air leaks from either of those sources will not cause it to die, it will cause high idle speed

I would agree to balance the throttles as first course of action
