1993 Voyager w/ 3.3 fails emissions test. Also getting code "21"

Failing idle speed emissions test. I checked the codes from the DRB
system, and I am getting a 21, which means that the O2 sensor voltage
is staying between 4.3 and 4.5 volts. Does this mean that my O2 sensor
is bad, and will it's replacement likely correct the emission problem
too?

If the sensor needs replacement, which one should I use? Bosch brand
has not had very good reviews in this NG. Which brand to Chysler use
for replacement?

Thanks,

Kirk Matheson

Replace the 02 sensor with a MOPAR part and be on your way!!!

Bosch O2 sensors are the ****s, even on old feedback carb systems. I
had one that was continuously cause mixture to oscillate between too
rich and too lean. Dumping it for a Standard stablized the system and
works perfectly.

I used NGK in my 1994, worked like a charm. Had teh shop do it, took
more time to write the invoice than it did to replace the part. $130
ballpark with taxes. CDN$

US$65, eh? Beauty, eh!

Yes, there is nothing like taxes to stifle the economy and suck the
$$$ right out of your wallet!

I do believe the part price was about $95, then about $15 to $20 to
install, then both federal and provincial taxes...

I generally find that the shift from USA to Canada and us$ to CDN$,
along with the need for local "wholesalers" to add their mark-up as
well usually results in what appears to be a 50% mark-up. So a $60 US$
part generally runs about $90 CDN$

And, unfortunately, it holds roughly true - yet again.

Uh...that's called the "exchange rate.'

I made a killing buying Canuckian dollars when Bush was letting the
Chinese sink the dollar.
