I did my first oil change on my 850 Turbo this weekend. (10-30 Mobil 1) Whilst on the lift I noticed that there were a few vacuum nipples thet are exposed. One is from the tube connecting the air filter to the turbo. (The nipple is on the bottom of the tube.) Then in the area by the fuel rail, there is a decent sized metal nipple exposed by the fuel rail inlet. Then on the bottom of the car, beneath the battery area, is a black canister with other goodies going to it. It has, as I recall, a few other vacuum lines connected. There is a nipple exposed on it as well. The car does seem to run fine, however I do have a re-occuring check engine light with 535 and 413 codes. Both of which I can safely attribute to vacuum lines being off, I hope.
Also, concerning brakes, I have noticed that if I pump the brakes several times while waiting in traffic, the pedal will sit up higher then normal. While driving normally I can feel the pedal go a bit lower than it would after several light taps. The brakes feel great in general, but I think that the vacuum system being less than perfect may be associated to this. Just curious if anyone has the same thing going on with their brakes. Also, as far as vacuum lines go, any help on getting these in the right places would be a great help.
Thanks

Thanks for the input. I plan on working on the car some over the spring, I will be testing the brake system just to be sure. The strang part is the fact that the pedal feels perfect all the time. Just seems to have its travel range move about. Guess I will find out what it is sooner or later.
