your original post said the garage flagged a code up for the o2 sensor...did they then clear that code, if they did, has the codes been read again since to see if that or any other code has returned.

chances are they told you it needed a new sensor because that was the code it gave.
number of reasons an 02 sensor code can flag....
faulty/ leaking injector, air leak, blocked breather, blocked exhaust/failing cat, ignition misfire, engine misfire/low compression/burning oil....plus more besides...in other words the car needs a proper diagnostic, otherwise you could end up throwing a lot more parts at it than you already have.
if i was you, i would start with checking for air leaks/blocked breather, if that is ok then next step get the emissions checked, CO/HC and Lambda..that readout can help pinpoint where the fault lies..ie, ignition or fuel problem
