1996 Mustang Engine Hesitation

I have the Trouble Codes P0141 and P1132

I just replaced my engine and when wiring the exhaust back up maybe i did a mix up or something because the trouble codes weren't on before the engine swap.

Anyway, During this winter when ever i hop in my car and take off it hesitates real bad like ill have pedal down on floor and it will not even go but as soon as it goes above 2.5 RPM though it will kick in and pull me but when the engine gets warm from driving it then the hesitation will stop I have No clue what is going on... Any Ideas?

p1132- Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank No. 1
p0141- O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)A code P0141 may mean that one or more of the following has happened:
  • open or short to ground in the wiring harness
  • O2 heater circuit wiring high resistance
  • O2 heater element resistance is high
  • Internal short or open in the heater element
a quick google of the codes gave me these..
if the wires to the o2 sensors touch, they can melt on the exhaust pipe which will give problems with the sensor being able to heat up they also might be backwards.. who knows
