  1. This may help, http://www.nissanpathfinders.net/forum/topic/45134-help-identifying-some-hosepiping-94-pathfinder/?tab=comments#comment-812720
  2. I don't have an external cooler installed at the moment, but I am considering it. I suspect it will get hotter than 175F when I have it loaded with all my camping gear. I am using this exact fluid:
  3. I've replaced the fluid, I was incorrect in my other post about mileage, there was easily 50k+ miles on that fluid you see on the dipstick above. I also just finished adding a tranny temp gauge, its tapped into the oil pan. Cruising on the freeway it sits right around 140F, stop and go traffic is edges up a bit to 150-160F. I put some load on it on the local mountain pass (sea level to about ~3000ft.) I loaded it up pretty good, it topped out around 175F by the time I reached the top. Don't worry, my wife leaned over to take this glare free picture. ^^^
  4. I finally had some more time to mess with around with the Pathfinder, I pulled the tranny dipstick and more closely examined the oil, see pics below. (I checked with the transmission cold and engine not running, so the level readings on the dipstick are not accurate.) It looks rather ok to me and it doesn't smell burnt, but it's been atleast 15-20K miles since it's last been changed so I'll go ahead and do that. I'll also look into installing a transmission cooler and temperature gauge to better keep an eye on things. What is the recommended ATF these days? I looked around at my local auto parts store and they are up to Dextron VI now.
  5. I noticed what looked like ATF dripping from a vent port above the passenger side wheel wheel near the firewall, see linked pictures. From what I can gather with a quick glance is that its related to the transmission, is this normal or does this require more attention? I noticed it after a I came to a stop after a long mountain climb, the engine did not get hot. It did not leak at all on the back trek down, nor did it leak during the 200 mile highway trip back home.
  6. UPDATE: Took my Pathfinder to another shop and it passed all tests, I have now blacklisted the first smog shop that did me wrong. Thanks all!
  7. Thanks for the suggestion Slartibartfast, that was actually the first thing I did before diving any further into the EGR system. I actually applied to much vacuum to the valve and the engine stalled, after that test I opened my FSM and checked the rest of the system, unless I'm missing something else I don't think there is anything left to do besides take it to another shop.
  8. Just had my 94 Pathfinder smogged last Friday and it passed everything except for the "EGR Functional Check". They offered to let me leave it there so they could diagnose but I decided otherwise as I know I thing or two about car repair and I also have the Nissan technicial manual for this vehicle. I followed the trouble diagnoses steps layed for the VG30E beginning on page "EF & EC-28" Checked for ECM codes on mode III and mode IV and received only received "55" (No Errors Detected) Performed EGR Function EF & EC-94 (No issues noted) Checked EGR Temp Sensor Resistance and hardness connector EF & EC-135 (No issues noted) Checked the EGRC-Solenoid Valve EF & EC-135 (No Issues noted) Checked the ERGC-BPT Valve EF & EC-135(No Issues noted) As per the above bullets, I could not find anything wrong, I don't know where else to go (unless the shop is lying to me). If anyone can offer some additional input I'd appreciate it! Below is the recent failed emission report, and another from 2014 (both were performed at the same shop), its surprising to me how close the numbers are from each session despite me having a faulty egr valve.
  9. I've had this happen twice to my 94 pathfinder and in both cases it was a failed fuel injector. I made a post about it awhile back here (http://www.nissanpathfinders.net/forum/topic/38258-replaced-timing-belt-now-running-rough/?do=findComment&comment=723973) I ended up just replacing all of them at that point as I got tired of removing the intake plenum.
  10. Right on sir! Replaced the distributor and the issue has been resolved, runs like champ now. Although now it looks I will be doing a head gasket job, its spewing white smoke all of a sudden,
  11. Had some time to tinker with the truck today, I checked multiple relays and isolated several different sensors with no changes. I also didn't have any luck in tinkering with the fusible link. Checking the timing was not possible, as the timing marks were jumping all over the place. As always the ECU is still indicating code 55 (no malfunction found) I did notice a connector under the driver's seat, it looks like it goes into a box labeled "Impact Sensitivity Selector" and then it goes off to somewhere else. I disconnected this on a hunch and the truck would not attempt to start. I re-connected it and the truck started up just fine, idled nice and smooth. I left it running for about ten minutes, shut it off and it started right back up no problem. Not sure if this disconnect/re-connect fixed my issue or if its just a coincidence. I will continue with experimentation.
  12. I am having a hard time believing that this is timing related as the truck will start and idle perfectly fine sometimes and other times do whats shown in the above video. The distributor is tight and has not changed position. I did a timing belt job last July of 2014 using all Nissan OEM parts, and following advice in this forum and by using the Nissan repair manual extensively, I am confident it was done properly. I have put about 4000 miles on the vehicle since the timing job. (I posted a thread about the timing belt/fuel injector job back when I completed it here). So far I've ruled out the fuel pump, fuel injectors, and all fluids are at the proper levels. I havn't had any additional time to diagnose since posting this thread, but as soon as I do, and if and when I find out what the problem is I'll be sure to report the findings. Thank you all for your suggestions.
  13. The problem started as I was pulling into a parking space, I put the truck into park and as I was reaching for they keys to turn it off, the truck turned off for me. Ever since then it's been acting like this, sometimes it'll startup and run just fine then die a few seconds later. The distributor is tight, no indication that this is timing related as far as I know. I will take your advice and tinker with some sensors.
  14. Pathinder is hard to start and runs rough at idle and the tachometer is very sensitive, no codes are being thrown except for code 55 - no malfunction found ​ ​Sometimes it'll start and idle fine, but then it'll turn itself off after about 10 seconds, other times I experience whats in the video below. ​ ​ ​ ​This leads me to believe its some sort of loose connection somewhere, I've checked/wiggled all connectors I could see and didn't notice any improvement.
  15. My 94 Pathfinder started running rough on the way home yesterday, the tachometer rendered itself useless and began bouncing all over the place and the engine started to run rough at low RPM. I was able to get it into my garage and pulled what I think are codes 23, 45, & 12. After pulling the codes I started the engine and it idled smoothly which leads me to believe it may be a loose connection of some sort. The reason I ask is that I do not see a code 23 in my Nissan repair manual. Video:
