Your 1992 Chevy Lumina will run with a bad 02 sensor. The engine will seem to be sluggish and the fuel mileage will go down.
It's an issue with an 02 sensor and the heating circuit to it. Not necessarily a bad 02 sensor, but the car is not going in to closed loop when it should. In open loop the ECU ignores the signals from the 02 sensors, during cold start until the sensor(s) are heated enough to go in to closed loop and the ECU uses the signal from them
A crankshaft sensor can go bad if due to an oil leak. If oil breaches the sensor itself it will burn out.
shaking jerking when pressing on gas
it could be the DPFE sensor that's what was causing my 02 to surge like that i was told that is a common sensor to go bad. it cost about 75 dollars and took me about 5 min. to replace.

The sensors that usually go bad in a Dodge truck are the throttle position sensor, the oxygen sensor, engine light sensor and crank sensor. These malfunctions can be fixed on any Dodge dealership.
tighten your gas cap, then leave the battery cables off over night and it should clear right up. if not, then your 02 sensors are bad......again. they go bad all the time. i bypassed mine with a sensor cause i live in the humid south and my ram runs lean because of this. if you live where it is cold then you maybe running rich. if an 02 sensor is off by.2% then it will cause a fault. correct air/fuel ratio is 14.1% and its nearly impossible to tune a fuel injection motor to those specs thus causing the 02 sensor to default
There are three O2 sensors. Bank 1 Bank 2 and a down stream one. Make sure your changing the right one. Get an O2 sensor socket. After your rx is cooled down, spray penetrating oil on the threads of the bad sensor, let it soak, go inside and have lunch. When your done eating unclip the harness of the bad sensor. Use your O2 socket and turn out the old sensor. Apply anti-sieze to the threads of the new sensor and install it. Plug it back in.
