Question about 1996 Nissan Pathfinder

1 Answer

5 speed 96 nissan pathfinder, the rpms keep jumping up and down making the car jump. took it to a shop for diagnosis and no trouble codes were emitted. the shop said that the on board computer system is not communicating with the engine. Are the symptoms consistent with the diagnosis? What else could be wrong with it?

    The rpms do not jump when idle. It mainly happens when accelerating

This may be due to sludge built up in the throttle valve area and also the automatic idle speed control valve, try cleaning them using the instruction below.
Buy a can of throttle valve cleaner (it is made by CRC) from the local auto parts store, NEVER USE CARB CLEANING SPRAY, IT DESTROYS THE ANTI-STICK TEFLON COATING, spray it into the air intake through the throttle body of the engine until you have used about half the can, you will need to hold the idle up while you do this, it will try to stall, after this shut the engine down and disconnect the Negative (-) battery cable for 5 minutes. The intake is now clean, if you continue to have the idle speed control problems you may need to seek the help of a professional

96 pathfinder stalls when engine gets warm


Yes it could be the MAF sensor. And that is one way to check it.
You may want to get a used one to find out. Could be something in the connector or wiring harness too.
Keep in mind when they fail they usually set a trouble code.

I have a 96'dodge ram 1500 4*4 when I get 55 mph the rpms bounce up and down. I was it feels like it trying jump in out of over drive any guess??


99 Dodge Ram 4x4 owner here also, Most Auto parts stores will do a free plug and play diagnosis if You can drive Your truck to them, That will give You the problem codes and if the salesman knows His stuff He can tell You the coded problem meaning and what part/service is needed to remedy if any, might just need a reset, I eventually purchased a DB II tester for myself as I have multiple vehicles and cant always get to an auto parts store, Good Luck

So did they clean the throttle body? It could be tps or iacv also. There are many things it could be. Is the check engine light on? If they reset the computer they should have seen what codes were present.

The EGR valve sticking, loose wires, bad ground connections, dirty connections, fuel pressure dropping out, vacuum leaks, or any combination of several of these at about the same time.
