Requests for DIY Project Guide

[2kBoxster]

I am now faced with the problem of replacing my O2 sensors as well. I would love to DIY and save some $$$, but I have not found a step-by-step instruction for doing it.
Did you ever get a response and instructions? Please let me know. Thanks.

Invest in the Bentley Manual for Boxsters via Amazon.com . It will show you have to replace them w/ a couple of pics. You can easy pay the dealership $400 for installation alone or buy the book for $67 shipped and dance around with the $333 you can spend on mods.

I have no clue where I got this from

-W/ the exhaust fully cold,raise the support car to access exhaust system.

-Remove rear wheel(I don't think this is necassary)

-Remove electrical connector from precatalyst oxygen sensor.

(You may want to use PB Blaster and let it do it's job for 10 minutes on the oxygen sensor-precat/postcat meet up point)

-Use an oxygen sensor socket or open ended wrench to loosen sensor and unscew by hand

-Remove eletrical connector from post-catalyst oxygen sensor

-Use an oxygen sensor socket or open ended wrench to loosen sensor and unscew by hand

Installation is reverse of removal,noting the following:
-o2 sensors come precoated w/ antisieze paste.
-DO NOT TOUCH THE SENSOR ITSELF!
-Torque to 37-44 ft lb

Good Luck! Hope this helps!

Hey Guys,

See if this helps: http://986forum.com/forums/boxster-general-discussions/9880-o2-sensors-questions-post85052.html#post85052

Good luck!

An additional consequence of any oxygen sensor failure may be damage to the catalytic converter.A rich operating condition causes the converter to run hotter than normal.If the converter gets hot enough,the catalyst substrate inside may actually melt forming a partial or complete blockage.The result can be a drastic drop in highway performance or stalling because of a buildup of backpressure in the exhaust system.If you're not sure how to exactly change your sensor,i suggest have the dealer to do it for you.

I have done it a few times and Blinkwatt post basically covers everything, it's a fairly straight forward project (easy), I would remove the tires for better access
