-40 degree coolant reading. no o2 readings
this is on hp tuners. did a t56 to 400 swap and the above is what i am getting now. the car is idling erratically. i have checked at least 10 times to make sure the harness isnt pinched or wires are cut. when i did do the swap i found one of the cam sensor wires was pinched in between the motor and bellhousing. i fixed that.

God hates know one..........., and yes i have checked and double checked the ground wire, fuses, volts to the sensors, resistance, pins on computer. i am going to replace the coolant temp. sensor and see what happens

Exactly, put a new coolant sensor in and I bet things will be good.
