Codes: P0031, P0142, and P1148 pulled from my vehicle. Looked them up to find: 1. Front oxgen sensor heater circuit low imput 2. Sensor circuit malfunction in bank 1, sensor 3 3. Air/Fuel sensor S connection Was told by a few different people I have a bad upstream o2 sensor. Was also told a bad bank 1 sensor 3, which seems to be a different sensor than the first one. Take two bad sensors along with an Air/Fuel one, and what do I have?? A TON of cash paid out on a vehicle that's under 42,000

Overheating fan will not run ! I change cooling sensor, fan relay,new radiator, thermostat, fan motor, check all fuses, tank low coolint sensor, put fresh coolant in also. (1998 achieva SL 3100 V6 SFI ) The only time i get fan to run is when i pull connector off cooling sensor. change this sensor twice to be shure. sensor has voltage on it about 5 v bench test fan also works fine. When coolint sensor is disconected the fan will run and keep running until i connect it back to sensor then it shuts

It is very hard to start when it is cold, my check engin light is on, i replaced the pcm, (with used rebuilt) same problem. i put volt tacometer on, it gives code, that my barometric sesor, air intake sensor, engin coolant sensor, top dead sensor, and throttle position sensor are bad. i also replaced the barometric/throttle position sensor, engin coolant sensor, i ohm'd out the throttle position sensor, i diconnected my battery, the codes did not clear,
This problem could be down to several issues all the way through from a faulty fuel pump to a faulty ECU. If the car has high mileage it could be related to poor compression in the engine itself which will make it more difficult to start when cold (r ... 1992 Eagle Talon
