Hey guys thanks for all the tips... Turns out it was a clogged Catalytic converter even though the thing was almost new.... I just bored it out... It's on craigslist for sale now gonna swap it for a hardbody with a 5-speed

Pulled the cap, it had some minor white deposits on the outer electrodes, center one fine, cleaned all leads and reinstalled... Found the TPS pretty easy, how do I check the output though? Also pulled air intake off to look inside at the throttle plate it's all clean and shiny still. edit -- I also read somewhere that it might be the auxialiary air valve. I've found where that is as well but not sure how to check it. Cheers

One of the stupider things I've done for sure. It gulped it down and died outright. Cap rotor and wires are all new since after the hydrolock. I replaced and flushed every part I could think off. So pretty new. I can pull it again and take a peek. Where would I find the TPS?

Yes, I've done some research on it and called the dealer even. Dealer mechanic doesn't know what it is, but did mention that in 99% of cases the knock sensor gets set off it's by something and not the sensor being defective. In 10 years he said he's replaced only one. So I have two conclusions so far... Neither very good. First is that the timing is messed up and needs work asap... But I don't know why it would only mess up at a certain speed... Everywhere else in my driving range is fine.... Which sort of led me to my second conclusion. The torque converter is on it's way out, which totally blows. I got some Lube Gard for it to see if that might help... If it is the torque converter I'm probably looking at a new vehicle. Other than that diagnosis, I'm not sure what else it could be..

B, yes the mud holds everything together down there.... I did check to make sure all connections were plugged in. I checked everything I could see it was all hooked up. I even cleaned the motor sort of lol

Okay just checked and it threw only one code. 34 - Knock Sensor. silverton - It will stick to 2000-ish and shake. When I force the tranny to shift it will jump to 3 or 4 grand and run smooth. Next question, is the knock sensor code a bad one to get? :S

6 days ago when I did the fuel pump. also did oil change, air filter, checked all other fluids and topped up if need be. I pulled spark plugs to check em all were good only 10,000 oil. regapped one as it was a nerd off. I will try checking codes tmrw AM, although engine light has never been on. Thanks edit - come to think of it, the tempature gauge gets shaky sometimes and dances up and down.

Hey guys, I tried searching this up with the search function but I wasn't having any luck (I'm on an iPhone), so I was hoping if I posted up maybe someone knows what's up. Here's my problem, it started a month ago with the truck bogging out when cold and having a rough start from a dead stop. Then it eventually just did not start altogether. Couple raps on the tank and off it goes, so I put a new (used) fuel pump in, and it starts fine now, but it still bogs out when cold and rough starts... However, I have a new issue now, when I am going above 60km/h to 90km/h and coasting at any speed in that range, the truck gets 'stuck' at 2000 rpm and shakes badly, can feel it in the steering wheel. I have to hammer down and force the automatic tranny to shift to make it go away. It never did this before the new fuel pump, but honestly I can't be 100% sure because I wasn't driving it a whole lot since it started messing up, as I got laid off around the same time (isn't that the way, truck breaks when I run outta work). I am going to be checking tranny/motor mounts tomorrow... but honestly I just don't really know where to start. I don't want to think it's the tranny, but it could be a real possibility, as it feels like it gets caught up in a certain gear-range and chugs until I force it to shift.. But I hope it's a stupid sensor or something... Really need some advice on this one. As I said I ran outta work and getting more sucks without wheels. Am driving a gas guzzling van in meantime and it's killing me on fuel. Thanks, Nade p.s. - The truck WAS hydrolocked 7 months ago but I drained vast majority of water and did new air filters and plugs etc before I restarted it, and it's been fine for awhile so I think it's unrelated but might as well mention it. edit--- almost forget the important stuff... 1993 Pathfinder 3.0L XE 4x4, automatic.

well i got the fuel filter for like 10 bucks and it took me all of half an hour to do it (including getting out tools and cleanup), so it's not really a bad idea.... its not going to hurt anything thats for sure.

A diesel pathy sounds awesome.

i did the fuel filter on mine and most of my issues went away..

I'm having a problem that sounds just like that. I took my MAF out and cleaned it really good and the problem became more intermittent, but it hasn't gone away. I'll be trying to fix mine too, as it sounds like the same issue, I'll let you know if it stops completely.
