p0325 code help! my girlfriend just bought a 96 cavalier and had 2 codes. p0325 and p0134. i know that the 325 is something with the knock sensor and the 134 is a bad o2. now my question is, to fix the knock sensor code will replacing the sensor simply fix it or is the engine done?

DTC P0134- O2 Sensor CKT No Activity (Bank 1 Sensor 1).
DTC P0325- Knock Sensor 1 Circuit Malfunction Bank 1 or 1 Sensor.
My guess would be to check your wiring for both of these and go from there.

It's idling like **** because your front o2 sensor isn't working. The engine needs readings from it to adjust fueling.
Like Diablo said, it very well could just be a wiring issue and the sensors aren't bad. Check the wiring before you buy new sensors.
And, no, this does not mean your motor is screwed at all.

Do you know anyone with a scanner or HPTuners that can scan your car to see if that o2 is working, you'd be wasting money by throwing parts at it, you need to diagnose the problem.

i would if i could afford it. now the cylinders were filled with gas and the car wouldnt start because of it. why would the cylinders become filled with gas? bad injectors/fuel pressure regulator?
