Check engine light came on, and see it is code 44 (O2 sensor, left bank). Are there any hints as to how to change the sensor? I am fairly mechanically inclined, but want to make sure changing the sensor can be done fairly easily. Any tips/advice? Thank you!   Tbow (Tbow) Member Username: Tbow Post Number: 77 Registered: 12-2002 Posted on Thursday, March 13, 2003 - 08:50 am:    Before you buy, check out www.oxysensensors.com I bought 2 for my 96 - 90 bucks each with free shipping. Just hope they're not frozen in.   Jason Gustavson (Prescottj) Senior Member Username: Prescottj Post Number: 469 Registered: 12-2002 Posted on Thursday, March 13, 2003 - 10:09 am:    easy job. In fact probably too easy. It's to straight forward to jack it up.   John Davies (John_davies2) New Member Username: John_davies2 Post Number: 11 Registered: 02-2003 Posted on Thursday, March 13, 2003 - 10:26 am:    Replace them both, unless they are fairly new.   Howie (Fritos) New Member Username: Fritos Post Number: 12 Registered: 01-2003 Posted on Thursday, March 13, 2003 - 11:27 am:    Thank you gentlemen! Much appreciated. One other quick question. The Disco has a hard start when cold (cranks for about 7 seconds, then it turns over), and when engine is hot, she starts right away, but quickly stalls. Is it possible the new oxygen sensor would remedy this problem? Thanks again!!
