Getting P0132 and P0152 codes. I have searched the o2 sensor wiring harness for shorts. Didn't find anything on PCM or +- battery wires. Have replaced the o2 sensors (AC Delco) and still Bank 1 Sensor 1 is continuous reading .875-.960mv at running temp. From a cold start it starts climbing from .600mv. and never comes down. Bank 2 Sensor 1 is .070-.545 at idle to 1200 RPM (its all over the place) and .650-.825 at 1500 RPM Both rear sensors are deleted from PCM but i am seeing them with voltage on my scan tool ??? Its a 96 LT1 Stroked 383 LT4 cam with EGR deleted from PCM. Fuel Pressure running is 45-47psi and takes about 8 hours to bleed to 15psi. Injectors are 30lb. HP is around 400. The only thing i hav'nt got an answer on is, The left converter is gutted and just a tin can at this point. I tapped it a little to hard (Clearance issue with Moroso oil pan) and shattered the inards. So i gutted it. I'm lost at this point. Can someone point me in a direction?
