o2 sensor stuck at .9 during idle?

[1glaserturbo]

Well I noticed the problem yesterday that my fronto2 values weren't cycling at all and were stuck at .9x so I replaced it with a new sensor. I started the car up again and it cycled just fine but I had to stop working because it got late. Earlier tonight I went to wire in my 3 bar map sensor and take the car out to make sure everything was working properly and noticed my o2's weren't cycling again. My wideband was reading super lean (18+) as well. Any help would be greatful!

Figured out the car was stuck in open loop with dsmlink, blah. Still don't know why though....ughh

The car is now running on 3 cylinders, I think it's a deac injector but the bad thing is I JUST bought them and they don't even have 1000 miles on 'em. Kill me now!

I have the same problem so i"m see who can answer the question.

Does anyone have an answer to this? My car is doing the same thing. It idle's really rough, o2 isn't cycling (at idle) and it's lean. What could be the problem? Come on in wisemen and help a brother out.

Well first thing is first, replace your o2 sensor. More often than not, that's the issue. I can pretty much bet that it has to do with some sort of maintenance issue. Whether it be a boost leak, crappy plugs/plug gap, insufficient fuel pressure, etc. I can't give you an exact solution because it could be a thousand things that cause the symptoms you guys are describing. Post a bit more after you've snooped around your engine bay and conducted some tests. Again, my first inkling would be a bad boost leak and a bad front o2 sensor.
