replace hardened vacumn lines,seemed to work better(was making a sucking sound on hills,ect)i found a split in 2 places on mine.Then the code 14 appeared,i blew threw the check filter and it was clogged,it should only blow through one way*make sure you remember what color is toward the tb ect.
Tranny also was shifting slow and never had converter lockup,trans shifts great,i gained about 20 hp easily and also when warm you had to depress the gas pedal to start it-im sure its cured!
