As I was driving, I heard this snap from the engine compartment that was accompanied by my rpm racing to 2000. I pulled over with the car in neutral and opened the hood while the engine was still racing. I checked the throttle wire and it was in the idle position! After checking for a possible cause, I noticed the the cap and insert for a component on the hose leading from the intake manifold to the brake booster was missing. I stuffed the component cavity with paper which allowed the rpm to drop to normal? To date, I have not been able to identify the component in a manual or Volvo vender parts list to order a replacement. I have surveyed other 1800 engine compartment photos and not all of them have this. Questions: 1. What is this component? 2. What is its purpose? Where can I get a replacement?
Thanks,
