fellas ive got an issue with my sc and im stumped. the problem is when i start she wont hold an idle for about five mins. after start .once she idles (when warm) it only lasts for a min or two and the just dies, like she just leans out to nothing. i scanned the car and the codes read as follows.

41 ego not swithcing exhaust bank 1

91 o2s not swithcing - ss1 check fault

31 eg (evp-ept) ckt out of range

ive done a bunch of stuff to the car that might be of help to a diagnosis,
swapped from aod to 5-speed , with manual ecm
head gaskets and light port and polish

if anyone has any ideas it would be greatly appriceated , i havent been able to drive the car in like a year or so and im losing the faith
thanx
