A week and a half ago I participated in a track day and gave the V8 and it's new suspension a workout. At the time I sensed an air leak by the pass side distributor. Durning the past week, idle has gone from ~800 rpm to ~1k rpm. Today while performing routine maintenence checks I decided to pinpoint the suspected air leak. I removed the air cleaner cover, air filter, and air filter to manifold plenum. I then inspected the rubber hoses and couldn't find any cracks (previous owner had replaced all rubber hoses). So then I decide to pinch the hose behind the engine that goes to the check valve and voila! air leak noise is gone. I follow the "relatively" hard plastic line and find a rip/tear at the area just forward of where the fuel lines are at the passenger strut tower. Ended up wrapping it with self-fusing polymer tape.
Result: Leak stopped, idle now constant ~650 rpm and the CRUISE control now works again after...could it be two YEARS??
Too early to tell if there is a mileage or performance gain.
