Hei, I've got an escort that was running just fine except that it was weaker that it should be, but when driveing the other day it started making a hissing noice (if I describe it correctly, sound like escaping air) and the engine started stalling at idle rpm. I could still drive it, but the powerloss is now even greater and it doesnt run on idle. After parking it in the garage to start debuging I noticed smoke in the engine room. The sound is louder than then engine and it gets louder with higher rpms. Any idea what could be wrong anyone? Thanks.
