I know it sounds kinda vague but maybe once a week/ two weeks my xj takes about 2-3 times longer to start then normal... Normally It starts right up but these few times it doesn't seem to want to... Any idea on what it might be?

 

Oftentimes dealers will ship vehicles around to get one with the customer's desired options. If you actually DO have a Bank 2, it's California-spec. Pop the hood and you'll see the mini cats in the exhaust manifold.

The OE for our Jeeps is NTK for O2 sensors by the way. Each one is a separate part number for some reason.

 

Yup your right I took a look. Two mini cats coming off exhaust manifold with each having an o2 sensor on top and on bottom totaling 4 sensors. If its worth anything the two top sensors look newer and the bottom two are old and rusty but guessing doing all 4 at once makes more sense just ain't going to be cheap.

Cleared the code and did a emissions readiness test with scan tool and Catalyst,Evap, o2 sensor and o2 sensor heater were all coming up incomplete. Now after taking an hour drive and doing test again o2 sensors are coming up complete again..

 

Is that just for 00-01 ? I was about to order some Bosch o2s for my 99.

 

I like NTK sensors more better.

 

I'll look for em.

 

Happened to know the part #s ? For ntk

 

Napa carries NTK.

 

I was bout to look on amazon. I'm ordering some other things off there.

 

That is worth something actually. A lot of people don't understand what the downstream O2s do on OBD-II Jeeps and often just replace the upstreams. I'd replace the downstreams and see if your code stays away. You'd also do well to check the fuses in the PDC. Sounds like your heater might not be working. don't forget to check out the wiring while you're there. Give the vehicle-side connector a cleaning.

NTK is a Chrysler thing actually. Bosch was back in Renix days. RockAuto's parts selector has the right numbers

 

Right on salad... whenever I can escape my toddler I'll look em up lol. Ntk is better for plugs too? I know I'm gonna need plugs soon wires look good but plugs are almost a year old now.

 

NgK for plugs. and yes, they are good. Same company as NtK if I'm not mistaken.

 

Ok so i asked this a few days ago, my tranny oil pan drain bolt seems to be stripped, i drained and refilled the fluid and the bolt never really seemed to get tight like it was when i removed it. It isn't leaking any, and it does have some tightness to it but it can just keep spinning and doesnt get tighter. You guys told me to replace the drain plug, now how would i do that? Does it require removing the whole pan? Because if thats the case ill just buy a whole new pan just so its all new. I cant find any info in the chilton on it, and google seems to tell me you have to remove the pan. Or should i leave it til it leaks? I plan on doin some wheelin this week for memorial day so not sure what to do here.

 

Wow I just realised I got those swapped around. Typing for my understanding...

NGK for plugs
NTK for o2s

Lol

 

Remove the existing plug. Put new one in, using new washer. The plug strips, not the pan. Get the new plug first. While loosening the old plug, use a flat blade screwdriver if necessary to apply downward pressure under the drain plug bolt head.
