I have an '00 Xj 4.0 with an aw4. The transmission is not original to the jeep since i converted from 2wd to 4x4. The tranny supposedly had 123k when i installed it 6k miles ago. Basically after installing the transmission i filled it up with dex atf and then started the jeep and tried to drive...

Alright guys, so update here... I took the throttle body off and thoroughly cleaned It and made sure the map sensor port was clear and I replaced the IAC with a “standard motor products” brand and It did not change a thing. I’m still having extended crank times just as before. Could a crank or...

Well guys i just wanted to update this in case anyone has the same issues down the road. I pulled the fuel rail and checked for leak down on the injectors and found that the injector on cylinder #1 was leaking so i swapped it out for one that doesn't leak but it did not fix the problem. I also...

So I've been having this reoccurring problem with my '00 where if my jeep sits for a short period of time (5mins - 12 hrs) it cranks for a while before starting and the only thing that sometimes helps is if i push down the gas pedal as its cranking but it still takes a bit of cranking to start...

A couple members here have had luck with the PSC 1205 pump. I just bought one but I haven't installed it yet. I should have it installed next week. Here's a thread on it. https://www.naxja.org/forum/showthread.php?t=1143323

So closed loop happens after It reaches a certain coolant temp? So what’s your interpretation of the data graphs I posted? Do you think it’s just lagging because I have too many pins activated at the same time? Sent from my iPhone using Tapatalk

Does It look like my o2 sensors are lagging or does closed loop last this long during initial running period after cold startup? What voltage readings should I be seeing within the first 20 secs of running after a cold start? Sent from my iPhone using Tapatalk

Yes but not anytime recently. I’ve been running the same 32s since the day I bought the jeep and It always averaged 15.5 mpg until now. Obviously I was getting marginally more than what the math came out to be since the speedo gear isn’t correct for the tire size but my other Cherokee with the...

So the speedo is off. I’m running the stock speedo gear in It with 32s and 3.55s. But even with It being off I’ve still lost 3mpgs since I haven’t done anything differently like correct the speedo (which would yield better mpg anyways) or change tire sizes or gears. The mpg drop happened on its...

If you pm me your email I can send you a video of the live data while driving but I can’t post a video on the thread. You also mentioned the electrical circuit of the o2 sensors and I did not find any chafing or melting of the wires for either o2 sensor circuit. Tim_MN

I just read through some of that thread and i see it's quite the touchy subject. You've got a guy claiming that his stuff is genuine and a lot of discrepancies in the product he's claiming to sell. Either way I've already swapped in a set of used oem Chrysler 1 hole injectors and the gas mileage...

I’ll try to post some screenshot of my live data of my fuel trims later. The o2 sensors seem to be fluctuating between their acceptable range but I’ll get you pictures of the data on them as well. I have not checked the sensor wire circuit. Do you have any diagrams of those for a 2000? I do...

So i just replaced both o2 sensors with NTK brand and i did a long trip with it today and i'm still at 12.5mpg. What am i missing? Could a bad manifold gasket cause a drop like this in mpg?

What was changed in the 00-01 model year that would’ve caused those complaints? All that comes to my mind is the LP d30. As for the OP’s question, there is no difference in a Chrysler 8.25 from a 2wd versus one from a 4x4. 2wd and 4x4 models share a lot of the same parts including the front...
