Camshaft position sensor ?

[Clipso 1]

Well I went out and started my car today(99 GST), well tried to start it anyway. It started up and idled rough as hell and sounded like a rod knocking but it was coming from the valve cover not the bottom end, and the car would only run for about 2 seconds or so. So I go in my house grab my laptop and go out start up the dsmlink and it had a cel that said Camshaft Position Sensor Circuit Malfunction. So I cleared it and it ran but was still idleing really bad and still sounded bad. I know if either one of the CAS are bad the car shuts off after 2-3 seconds, but would that explain the rough idle and noise? I am buying another sensor on thursday when i will have enough time to put it in. Any help would be great, I'm just trying to make the car as realible as possible since I just found out my wife is pregnant so I cant afford to keep building it anymore.
Also I cant keep an O2 sensor working in the car, like even with a brand new one it says it isnt workng after a day or so, any idea why?

Thanks,
Jeremy

The CAS being out will typically cause misfiring. This is most likely what you are hearing.

check your timing i bought the sensor (havent put it on) i checked my timing and it had jumped alot of teeth, so I retimed the motor and everything is fine, didnt even need the sensor.

Will the check engine light come on if the CAS is bad on a 1g?
