I just got a “check engine light” on my 2001 Boxster at 34000 miles. No engine performance decline, just the light coming on. Bought an Actron code checker and got “code P0134” for bad oxygen sensor.
Based on reading other threads on this site, I should probably replace all 4 sensors. What is the current thought on the best place to buy O2 sensors with the correct wires and plugs attached?
Randall Neighbor previously suggested
www.oxygensensors.com as a good place to get them at reasonable cost (today = $77.52/each at
http://www.oxygensensors.com/catalog.php?&pkey=1374836).
I’m wondering if these are good ones or if I should look somewhere else for Bosch units.
Any suggestions appreciated. Thanks.
