Have you used a scanner to confirm that is sure the Lambda sensor?
It is good if you can ,use the scanner and check for the fault code given by the vehicle ECU,

There is sooo many problems with the 1.8ltr engine (2001) ..for example the oil ports in the cylinder head casting are way too small.. this causes clogging and obvious lack of flow and then lack of power due to compression ratio going out the window.. I've re-built quite a wee number of these puppies.. including my wife's own car..so I heartily recommend the below..
1/ THOROUGHLY FLUSH EVERY LAST BIT OF GRIME, DEBRIS, LACQUERS & OIL OUT OF ENTIRE ENGINE..
2/CHANGE FILTER & REFILL WITH SEMI-SYNTHETIC 15/40 OIL..
3/ OIL AND FILTERS MUST BE CHANGED EVERY 3,000 TO 6,000MILES TO MAINTAIN ENGINE (IF NOT BORING OIL PORTS AND QUITE SUBSTANTIAL WORK & EXPENSE)
This should give immediate effect, but you may also consider the CRANK/FLYWHEEL SENSOR.. It's NOTORIOUS.. Along with the IGNITION COIL PACK.. CONSTANTLY CRACKING HIGH TENSION LEADS..Etc...
Hope this helps someone out there..
you need to get an OBD scanner plugged in . auto zone or advance auto or most other parts shops will read computer codes for ya.
