Re: 89 Cherokee failed emissions - HELP!
It would be less expensive if you found a shop, or person, that could plug
into your 89 XJ to see what the ECM sees! A good shop might have one of the
Snap-On Scanners that might have an adapter to hook up to yours.
19 lb fuel injectors sound right BTW. ;-)
good luck,

Re: 89 Cherokee failed emissions - HELP!
Dave, the shop I took it to is an authorized emissions repair
facility. They had it on the scanner/analyzer and what they tell me is
it shows that the O2 sensor is not going into closed loop mode. Not
sure if I have the correct terminology. Most of the feedback I get it
seems that the ECM is what goes into closed or open loop..?? I am
going to let the Jeep dealer put in the OEM O2 sensor (free on a
recall) and then look at all the sensors input to the ECM. Could be
that my ECM is bad...??Thanks for the info about the 19 LB fuel
injectors. Any input is most appreciated.
All the best, Randy

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!
later,
