Engine has been running well since the rag was removed. It has been experiencing a fluctuating idle. Found a vacuum leak where the HVAC actuator feed line passes through the fire wall. The original plastic line has become brittle on the engine side of the firewall. Replaced about a foot worth of the plastic line, a bit on side of the firewall. So far so good.
