1994 Nissan Pathfiner is not accelerating like it should. Can anyone help?
I can't tell if it is the Engine or Transmission. But I just bought this pathfinder a few months ago from an older couple who kept it in mint condition. I have had no problems until now. Whenever I press on the gas it hesitates to accelerate as soon as it hits like 15 mph and at 35 mph. So I have to let off the gas and put my foot back on it. That seems to work a little when I do that, almost as if was a manual transmission and it can't find the gear unless I let on and off the gas. Also when I get up to 30-35 mph it does the same thing were it doesn't want to accelerate anymore. Also the RPMs gauge doesn't want to go over 3, so i let of the gas for a second and step on it again. It seems to be getting worse and I need to find a solution soon. I had a problem like this with my old Toyota Corolla and it turned out to be spark plugs. But the couple I bought it from said they just had a tune-up. I checked all the fluids (Oil and Transmission) and they seem to be fine. I can not afford to take it anywhere to have it looked at because I am struggling financially with two kids. I feel like I am running out of time. My brother said he can fix it for me if I can find the source of the problem. But he doesn't know what it is. He doesn't really know a whole lot about cars. If anyone may have any suggestions I would most appreciate it. Thank you.

1. Transmission fluid level
2. Engine idling rpm
3. Accelerator pedal position (APP) sensor
4. Line pressure test AT-66, "Line Pressure Test"
5. Line pressure solenoid valve
6. Control valve assembly
7. Transmission control cable, if any.
8. Short circuit in wiring harness.
The over drive switch may be shorting or the over drive solenoid is damage and needs replacing.in either case this needs to be checked by an expert.Do not attempt to fix this because it may cost you an entire transmission.
hi,the accelerator pedal can be blocked, which causes it to have a high idle.well what you have to do is to see for the cable for the accelerator, which come on the injector pump.now you will see the cable attach to a rack on the injector pump,this rack has a movement position ,when you press the accelerator pedal it moves to the accelerate position.now what you have to do is to move the accelerator rack to the decelerate position,then after doing that start the engine,see the idle what it give.it should be lower now,put some penetrate oil to the accelerator rack,for the move to be free.hope that help you
Whining noise is worn gears or low on transmission fluid. It after reading your post, sorry to say but you were low on transmission fluid and your transmission needs to be replaced. You gear box has seized and every time you release the clutch even in neutral will kill your engine. The transmission shaft may have seized on the bearings in the transmission case, regardless you need a new or rebuilt transmission. Good luck friend and sorry for the bad news. Keep me posted.
My bet would be a transmission problem. Worn clutch material, worn gears, worn bands. Several issues like that, when you check the transmission fluid feel it, if there are metallic, or other particles in it there could be some transmission wear going on.
It's also good to remove the transmission oil pan and take a look at the fluid in there (keep in mind, doing this will drain the transmission of fluid) the reason I say that is almost all transmission oil pans have a magnet to collect metal particles and keep them from entering the filter, so checking the dipstick there is a less likely chance you will actually find metal particulates.
I hope this helps. If not, let me know what you did, and have found I will try to help you more. Add details, the more I know the easier it is to tell you what could be wrong.
