This automatic 626 runs rough when put into drive or any gear other than neutral or park.  Also not shifting out of 1st gear when cold.  It came to me for a Halfshaft and now is shifting bad and running rough.  The customer is less than happy.  It totally looks like I broke it.  So i find the EGR clogged full, i fix that and is now running better at idle but rough and low idle when placed in gear.  I fixed two vacuum leaks and tested the MAF,  The front o2 is low voltage around 0.1 - 0.35 at best with an occasional jump to 0.55  According to the book it should hold above 0.55   I'm replacing the 02, plugs, cap & rotor.  It hasn't had a CAT for years.  Still running rough.  Any advice out there for rough idle and acceleration when put into gear?
