Well my cutting out/staling was determined to be b/c I am missing one o2 and downstream that's on there is not working. This is per a Jeep mechanic that had the computer hooked up while driving today. Just wondering what kind people have used to replace bad ones those that have replaced them. I saw the
Bosch Premium Oxygen Sensor


Part No. 13100

On Advanced Auto Parts site for $62.99 each. which look decent. I need to get these to install tomorrow. thanks for any input in advance.

 

That's what I've got, no problems to report...

 

You get what you pay for in most cases. Spend $63 once or $25 three times, you decide.

 

I was actually wondering if the more expensive where better, haha. These seem to have great reviews. Let's hope! Thanks guys

 

Jeeps don't like Bosch oxygen sensors they aren't the right style and don't have a proper switch rate especially if you have the 4.0 with the four o2 sensors...for those who don't know their are three distinct types of o2 sensors and yes it does matter...

 

So what kind do they like? I just installed on of these on the downstreame and still having issue, if I install the upstream and its still doing it, I will be upset and need to know what to replace with. thanks

 

I got all four Bosch o2 sensors from amazon for 160$ which is almost half the price of most other places...because I have the Ca Spec Bosch makes a different sensor for each spot apparently ... I plan on installing them later this week.

 

about a year ago I got 2 new Bosch O2 sensors from Car Quest. I installed them a while ago and can't remember if they helped or not. I've had a problem with my Jeep when it's warm misfiring and wanting to stall out on me. When I give it a WOT it runs great. At low idle it sucks bad. I've checked my wiring and fuses, tested parts with my multi-meter, and replaced a lot of parts already. Some parts for maintenance and others for this issue. here are all replacements in past year: plugs, cap, rotor, wires, coil, injectors, fuel pump module, muffler, cat, Crankshaft Position sensor, IAC sensor, IAT sensor, MAP sensor, TPS sensor. I removed the throttle body and cleaned it out really well.

I'm going to try putting on an old O2 sensor and see if it still runs the same. That might help me figure something out.

You guys have advice? I'm literally going out of my mind and broke finding this. I've spent last 2 weeks with my multi meter testing resistance of wires and voltages from the PCM. I've found nothing wrong with the wiring or electrical, or fuel.
