quattro digest, Vol 1 #3669 - 5KCSQ hard start/idle

[Larry C Leung]

You've a vacuum leak. First check the Michelin Man hose (see
sjmautotechnik.com
if you're not sure what that is) for leaks. MUST be a car off inspection,
check the underside
for cracks or leaks caused by intake oil in the hose. I've also "played"
it like an accordian,
sealing the ends FIRMLY with my palms and compress. Should not leak air
and compress,
if it does, it's got a leak. If so, TPC (the Parts Connection, see vendor
list) of Double Z Motors
(also on the list) has 'em for about $35. Otherwise, check the valve
cover gasket and all other
vacuum hoses.
