We have been running into some probs with the
bosch o2 sensors 3 so far after about 30 to 40,000
miles they have been leaning out and trucks have
been running very doggie

Either get one from mopar $102 or goto NGK and
get a NTK same as factory starting at $44 for the
obd1 trucks they have been running with no truble
up to 100,000 miles

Not all the sensors did this the first one I ran
into I thought the truck had low fuel presure but
it did not

Wathing the o2 on the scanner it looked ok and did
not trip the code still pulling my hair out with
the lean smell poor performance and piston ping
I than taped the o2 at the computer hooked it to
a ociliscope to watch the wave form that is when
I found the problem

If you have these symtoms and have good fuel
presure and all other sensors are ok I would than
suspect the o2

I forgot to add this was only 3 out of around 41
bosch sensors we installed so don't jump to
conclutions but it is something to watch for

We are now using all ngk ntk sensors in the shop
to avoid this from coming up again but you never
know what can happen

I have been hearing people say bad things about Bosch O2 sensors for awhile now. In my car the original sensor lasted 190K miles. I replaced it with a Bosch and it's been 4 years and 67K miles, and I just passed emissions with flying colors - no problems at all. I don't believe this is a widespread issue.

a 7% failure rate is not what we expect when we buy parts but it sure is of less concern than say a 50% rate. As Wadak said it gives you a place to look when your truck is not running right.

I thought i responded to this thread ealier but I guess not.

I noticed this in my old 95 CC 4x4. I replaced the original o2 sensor in summer of 2004 with one from advance, both were bosche. I traded the truck in for an 02 QC 4x4 in early jan.

In the month leading up to me trading it in, I noticed some performance issues and finally it started throwing O2 codes. Having just replaced it a year before, I assumed it was good. Took it to a shop, they watched it on scanner and found no issues. Finally, getting frustrated, I replaced it with a new one. I decided to test both using my torch and multimeter.

Both tested out of spec. The brand new one, more so than the old one.

Larry - did you ever test those "bad" sensors with a multimeter and torch?

I just got all 4 sensors and still have my codes. Both Bosch universals but it still gives me the 132,136 and a few others...I will try the NGK's on the pre cat side to see if this would help...
