Hopefully not a rant really.

Oxygen sensors:
The regulars here have seen this info, and the FAQ now breaks out the difference in titania sensors for Regina, but new brick owners come along all the time and the if you go to some otherwise well respected parts sites like FCPGroton and IPD, you will be sold a generic zirconia sensor which will not work correctly on their Regina 740 or 940, though these sites do sell the correct direct fit starting upwards of $130.

Thanks to Lucid, I recently bought the right, direct fit, sensor for $99 plus shipping from sparklplugs.com (NGK's site). See the thread where Lucid points this out at
O2 thread

Or go directly to NGKs site
sparkplugs.com
and enter your car's info to move on to the right sensor (but be warned, they seem to think all our cars have 16 valves)

Also on the NTK site, I found the best tech writeup (in English, at least) on the titania sensors I have seen so far
titania text and charts!

Since it's my birthday, I thought I would vent on my pet peeve. (I put "please stop selling the generic Walker O2 sensor for Regina" in the comments box every time I order from FCP.) Thanks for reading.

btw, Regina owners: Don't pay $120 for the fuel pressure regulator specified for Regina, buy the $40 one for Bosch LH 2.4. Works great for me.

    Good deal ,and happy birthday! I guess you and Bruce got to be the test subjects to see if they were the correct sensors, and not the Bosch Zirconia types in disguise. Those NTK sensor part #'s should be added to the 700/900 FAQ so other folks can order the correct Regina replacement parts, and save bucks too.

    Hi Andy,

    My 25002 came a few days ago too and it's now installed. Can't say the old one was slowing down (didn't even bother to meter it). But mileage was a little down on my last trip -- maybe winter gas -- so with 152K on it, I decided to just replace it.

    Thanks for the post and links. I recall reading the NTK Titania blurb, now that I see it again. I guess we've put this issue to bed... for now.

    Bruce

    That's not what caused your O2 sensor to go bad was it? Actually I doubt it, but I am a little curious if your old regulator went super-rich just prior to the O2 sensor going bad.

      My O2 sensor didn't go bad. I just took the opportunity to see if one of my three Regina cars would get better milage with a new sensor instead of the presumably original ones they all had. Plus, now I have a spare in case one does go, or I want to diagnose.
