Brake Booster Vacuum Issue??
Hello all! Model 2010 Alfa 159 JTS 2.2 - So i returned from a short 2 hour trip driving some pretty intense terrain not long ago. Whilst stopped at the first set of lights back in town my revs have dropped to about 500rpm with a really rough idle..... Symptoms now are due to extremely low revs, stiffness in brake pedal along with strong smell of fuel both in and out of the cabin.... My suspicion is a vacuum leak possibly near or at the brake booster. I have checked the air filter, and all gaskets around the block. There is no real obvious hissing noises although my ears are definitely not tuned to this sort of noise. Any other suggestions? If this is the likely culprit, where the hell is the location of the brake booster???? It looks like the vacuum line runs into the cabin on the drivers side? Do you have to rip everything out of the dash to get to it?
