duplicate question

P0141 - O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 2
Possible causes- Faulty Rear Heated Oxygen Sensor Bank 1
- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Inappropriate fuel pressure (to high)
- Faulty fuel injectors
- Intake air leaks
- Exhaust gas leaks

I have a 2001 Silverado 1500 with the 4.8 that had the same error codes. It turned out to be intake manifold gaskets were bad. With the engine running spray some carb cleaner on the intake where it bolts up to the heads and listen for the engine to speed up. If it does you've got a leak. With mine I couldn't find the leak with the carb cleaner but after I replaced the gaskets the problem was solved. Hope this helps.

throttle position sensor can cause the high idle as will a hole in the egr valve tube as far as stalling as soon as u put in to gear could be torque converter not unlocking but id check the egr tube first

some of these get seized in the threads so yes you might have to heat the area around were it is threaded into the pipe to un seize it.

o2 sencers or water pump

Yes they are i would try and change the o2 sencer first.Because it says your system is running to lean or to rich. And that 02 sencer is the problem

Its on your exhaust. There can be 1 - 5. Your van probably only has two. There is an upstream one (Before the catalytic converter) and a downstream one (After the catalytic converter)

what is the year make and model of the car?
