You likely have a broken or cracked hose that goes into the intake manifold. Very common on VW and Audi...Google.com the terms and you'll see detailed discussions.
Ok this is a mustang V6...not one of those vehicles above, i pulled the plastic air intake ducts outr/frt. (air filter ducts)checked the barrel plug connector mounted on top r/frt frame rail under the air ducts, was OK. know to rot and fall apart, making the coolant fan inop etc. Next I pulled out the r/ft. inner wheel skin and pulled off the air pump hose off the electric smog pump, started the car found no air pumping out of the 3/4? hose, replaced the smog pump located behind the r/frt parking lite cost 205.00 from Ford checked after replaced was now pumping air, cleared codes good to go for weeks now!! clear codes with a hand held scanner not by battery as you will clear all the drivability codes out of the computer basically giving the ECM a phlebotomy, it then has to relearn all its driveability sensor inputs again why do this when a 89.00 scanner does it quickly easily and safely.
