I changed from a lq4 to a lq9 01 to 04 and installed a 3000 stall at the same time. It will start and rev but will not idle and no dtc. what is next? Thanks Woody

Woody,
The PCM uses CASE relearn to "calibrate" it's misfire detection algorithm.
Changing converter changes the rotating mass, so a CASE relearn would be required here.
The idle problem requires tuning of the idle tables/parameters, of which I am not yet proficient, so I'll let knowledgeable people chime in.
Cheers
Joe
