I agree - continue looking for vacuum leaks. The vacuum bounce at 15-16" at idle and drops to 13-14" when put into gear (measured at ignition control vacuum port with tee connection). Anyone know what is common to these cars for leaks? EGR replaced with leak. Transmission modulator checked. Rubber U shaped tubing under plastic intake box to idle speed seloniod replaced, rubber tubes from same seloniod to valve cover & air cleaner replaced.
