Well the title on my Grand Prix cleared so I celebrated with the cheapest upgrade on my car. I replaced the PCV valves and check units and used 20 feet of 3/8, 1/4, and 5/32 vacuum hose. All the ones carb-related, vacuum canister and its lines, all the lines from every vacuum unit on my car are nice and shiny black now. Whoever rebuilt the engine had poor vacuum line and carb hygiene. I bought a GM service manual on ebay and took pictures at a salvage yard. I've added more (and bigger wherever possible) vacuum lines to the setup because so many were unplugged or didn't go anywhere. But, there's a lot more room now due to how I re-routed everything. It's t*ts! The only thing I removed was the check unit that goes from the fat Q-jet to the vacuum purge valve in a 3/8 inch line. No other car I saw in a salvage had one so I tried it out. The car runs real smooth now with the vacuum job complete. Operation Suck was a great success 8)
The hose line from the vacuum control (up by the other sensors and devices on the front of the engine) goes past the AC compressor, through a check valve and into a module or device mounted on another device. That final device attaches with hoses and other crap to the AIR pump. The device attached to the AIR pump with hoses also has big hoses that go toward the firewall. I have one that goes nowhere, just a big unplugged hose about a foot long. I never even noticed it before, not until after I was finishing up the three hour suck job. I didn't realize how much stuff I had removed from my engine compartment! Where does that giant air hose go to? Mine still has the clasp retainer on it. I figured that AIR pump attached device would be a vacuum flaw in my pristine setup, so I plugged the b*st*rd going into it from the vacuum control.
I'd like to get that big hose attached to something proper, and then plug my other vacuum line into the module device thing so that everything is perfect. Anyone know the deal? If I do get it attached to something, will my car even run even better than it does now, or worse I don't want that!
