P0171 is a lean exhaust code, typically due to a vacuum leak or air leak after the MAF sensor. There can be no air or vacuum leaks.

P1349 is relative to the variable camshaft timing system. A new cam sensor will NOT fix this trouble code. The code is set because the computer is commanding the camshaft to advance, and it is not responding. Most commonly this is due to either the camshaft solenoid, or the camshaft sprocket on the engine. There are ways of diagnosing this, but if I needed to take a guess at it, I would probably put a camshaft advance solenoid on the car, clear the code and see if it resets, as this is the cheapest and easiest component to replace for this trouble code. The cam advance is also very reliant on clean oil, if you have not changed the oil in awhile or if it's low, take care of the oil and filter.
