 Yeah, it was one PSI at curb idle over the spec, so I figured that was good enough. Take a look at the map sensor. Key on, engine off, you should see four to four and a half volts. Start it up, you should see a volt, volt and a half, something like that, but just be specific. Propane the throttle body. Just make sure there are no vacuum leaks elsewhere. Leave the brake booster disconnected.
