I ran the KOEO/KOEO and cylinder balance tests using the jumper. The good news is my CEL flashed the codes. The bad news is I've got a number of codes. I installed a 4R70W transmission recently. Up until that point the car ran great and was not setting any CELs. After install the car acts like it has a miss, especially at lower rpms. It kind of "chugs".
The KOEO codes I pulled were
111 System pass
172 right o2sensor lean
176 left o2 sensor lean
181 right side o2 sensor rich
189 left side o2 sensor lean
332 EGR not opening
628 converter lockup failure
The KOEO codes were
172
332
536 Brake on/off failure
632 OD cancel not detected
im not certain I understand how the o2 sensors could read rich and lean. The EGR I can look into. What are my options on the trans codes. I know a tune will correct the ratio error, but it has all the original solenoids and MLPS. I didn't think I would have any problems with the tq lockup
TIA
