1999 Saturn SL2

Engine Performance problem
1999 Saturn SL2 4 cyl Front Wheel Drive Automatic 114, 00 miles

I just brought a 1999 Saturn SL2 from a friend. This friend said, it may need some work to pass emissions. After driving for 4 days, the check engine lights came on. I ran a scan and got these codes P0341, P0133, P0133P. Any help with what's wrong.

For the p0133 that's ur front o2 sensor u will need to replace the o2 sensor in ur exhaust manifold to fix that code. On ur p0341 that's the cam signal postion sensor which the car doesn't have it's usually plugs and wires if u take the spark plug wires off take a bright flash light and look into the boot end that goes onto the plugs look for a black powder that's carbon if u have some replace the wires. Also remove ur spark plugs and if u have black spots on them that's does wipe off or tip that goes into the engine is worn replace those as well. Let me know what u find.
