It can not be adjusted i would check the catalytic converter sounds like it may have had a melt down causing it to get clogged which would make it loose power.

SOURCE: my car will only rev to 2500 rpm in drive or in

Most Japanese manufacturers protect their engines from over-rev by programming the ECU to limit rpms when vehicle speed is zero. 2500 rpms seems low. Usually it is in the 3500-4000 rpm range. Is this car new to you or have you had it a while and this is a new observation?

SOURCE: 92 300zx rpm will not go over 2500 rpm pops from intake

This is a classic symptom of a bad mass airflow sensor. Nissan designed this as a protective feature on the car. If the mass air sensor goes bad, the computer limits the car to a 2400RPM rev limit to prevent damage.

The sensor is under the center nose panel between the headlights. Take that off and on the back of the airbox (which fills this space) you'll see a pipe coming out that meets at a "T" with another hose going across and down under the headlights. That pipe off the back of the airbox is the mass air sensor (it has a harness plugged in).

SOURCE: upgrade 4.3 l carb engine to vortec TFI fuel system

It can be done but it is very time consuming.
I use an 87 Astro van intake sensors and computer on my 86 OMC.
After six years I am still playing with it.
Runs good and easy on gas.
Got lots of info from DIY-EFI.
You HAVE to change programing in the computer.
I am running a closed loop system with one oxygen sensor in the starboard manifold.
Your 94 computer is not as good for a boat because it also controls the transmission.

Just to give you an idea what your in for.

Change your Thottle positioning Sensor. My 93 lesabre did the same thing and i changed the TPS and it stopped.

SOURCE: 1993 toyota 4x4 idle problem

sounds like your throttle positioning sensor is not set right so i would undo the two phillips heads that hold it and turn it till the idle doesnt fluctuate should be turned most of the way to the front of the truck. Also check your idle screw that throttle body could be set different.

Does a 1988 carborated Nissan pathfinder have a fuel pump regulator?


Are you sure it is a carburetor and not throttle body injection? They do look similar.
If it is a carburetor, there would not be a regulator. The fuel pump will either be a mechanical pump mounted on the engine, or a low volume electric pump in the gas line from gas tank to the engine.
If it is throttle body injection (TBI), yes, there is a fuel pressure regulator, probably located near the throttle body. It will have gas lines connected to it (one line will be a return line back to the gas tank) and a vacuum line. The fuel pressure on TBI systems is not as high as multi point injection, usually around 20 psi. You would have to check the specific pressure requirement for your pathfinder.

Take off the air cleaner cover and look at top of unit. A carburetor should have a choke plate right at top of the carb throat. However some Nissans by '88 had a carburetor without a choke-it used an enricher jet controlled by the ecu for added fuel when starting.. On a TBI, looking down at the unit where the air goes in, you will see one or two injectors with a wiring harness connected to them-each injector will have two wires connected to it.
If still unsure, check engine designation on the under hood label. Carbureted engines will have a s letter designation, injected engines will have letter i. To explain: my '87 Sentra is carbureted, so engine designation is E16s, some same engines were injected, so their designation is E16i.

Loss of power diesel


This is causes by either a defective injection pump or low fuel pressure in a digital injected diesel. If it does have digital injection you must have the system scanned for fault codes and the fuel pressure tested for proper PSI

Locate carborator on Chevy cobalt 2005


The 2005 Cobalt is fuel injected. It does not have a carburetor. If you are looking for the fuel injector it will depend on if it is thorottle body injected or direct port injection. Typically they are throttle body fed cars. Follow the air cleaner box up and the aluminum .housing will have the fuel injector in in.

1997 honda accord ex idles at 400rpm when warmed up how do i adjust it to raise it lil bit


If this is fuel injected with actual injectors you may find an adjustment on the throttle cable at the motor. If it has what appears to be a manifold mounted carborator there will be a throttle idle adjustment that you can adjust to increase idle.

Fuel not getting to carborator.


The filter is external. Located on the passenger side frame rail, about 4-5 ft from the tank. round, metal (or if previously replaced-- might be plastic). Are you sure you have a carb? 1988 models were throttle body type fuel injection. If it is TBI, you may not be getting power to the internal fuel pump. Are you seeing a fault code (the check engine light flashing)?

Not getting any fuel thru da engine


the car is low on compression so you could have a hole in a piston or a bad valve the pistons in this engine are its weakest point especially if you try to crank up the boost to far above stock they can only handle about 14psi with ocasional trips above that.
also these cars do not have a carb they are throttle bodie injected so if you check your compression and is ok then try injectors
