Re: 89 Cherokee failed emissions - HELP!
OK
It is not going into closed loop (when the 02 sensor comes online)
.............Now why is it not going into closed loop is the question!
Yes it could be the 02 sensor.
Also it could be a temperature sensor problem causing it not to go into
closed loop.
Yours was WAY too rich so I would suspect a temperature sensor problem. :-(
And I will ASSuME that the fuel pressure was checked. I think you indicated
that it was.
That shop should have been able to tell you what else was not right.
Let us know!

Re: 89 Cherokee failed emissions - HELP!
Thanks to everyone for the input, it was all helpful. Mike Romain hit
the nail on the head. The Bosch O2 sensor was the problem. Took the
Jeep to dealer for free recall install of new Mopar O2 sensor.
Immediatly took the Jeep to two different emissions test facilities.
It now passes easily! Where the HC was in the 300+ range its now in
the 20's. The CO is almost unmeasurable. Fantastic. Well you live and
learn..Dont run down and buy any old O2 sensor..maybe you will get by
with it but I sure didnt. Thanks again and all the best.

Re: 89 Cherokee failed emissions - HELP!
Hi Randy,
Thanks for telling us. Yours is the first oxygen sensor I've heard
of the the Stealership eat, but then I've never heard of a recall on
them. I bet you'll realize better gas mileage too.
