Power Valve Failure by powervalve

I have a 2004 Pathfinder that had the power valve screws in the intake back out and fall in the cylinders and fry the engine. I have 33,000 miles on the car, but I am past the warranty period by six months. Nissan refuses to replace the engine under warranty. This is the same problem that the Altima's and Sentra's have seen which is recorded on TSB NTB05-058. I am writing letters to both Nissan North America and NISSAN Motor co. I have also contacted Newsday and will be sending them all the info. If anyone else has had this problem, please contact me at un33dityahoo.com so I can have more info to fight with.
 
Thanks,
Gary

92 Pathfinder engine stops/dies while moving. by raulroa

I have a 92 pathfinder that in the last year, I replaced the engine, starter (2X), battery & battery cables and it still does the same thing.
 
While moving, it "stalls" and all the engine lights come on, then they go off.
 
Sometimes I am able to put it in neutral and turn the engine key again and it starts. Sometimes, I have to pull over with a dead engine and try to start it. Sometimes it takes a few minutes for it to start sometimes longer.
 
When it stops and I park it, sometimes when I turn the key again all the engine lights go on but it won't start. Sometimes, no engine lights come on at all. I've had it towed to mechanics and I have waited for it to start on it's own.
 
In the mean time, the clock, door chime, door lights and lights work when this happens.
 
What do you think this is and how can I get it fixed because it is costing me a fortune with the mechanic every time (dealer, regular mechanics) no one can find the problem when it is with them. They replace things, but later on, a few months later, the same darn thing happens again. Please help.

I have a 95nissan pathfinder 4wd 200k miles. The engine light has been on for about 2 years I thought it was just a oxygen sensor so I just replaced it and it still does that. I may start it in the morning and it will rev like normal then idle back down while driving engine will jump back up and rev and belts will squeel and then it may or may not go back to normal idle sometimes it will stay reved all day sometimes it will randomly drop and go back

I looked today at ir and the hose was completly broken going to the EGR valve, replaced it and cleared the code and the light went aeway for a couple of hours now it's back. Pretty sure I need to replace the EGR.
