Hi Shane,I have a 85 Nissan 720 4x4 with the 2.4 engine,had her for 22 years,our trucks have bad carburators,when I bought mine used,it had 108,000 miles on it and my carb started giving me problems,with the ideling,took it and had it rebuilt by 3 different carb shops at 200 a whop,no one could get it right,so I took it to the Nissan Dealer,they told me that they couldn't rebuilt it cause the bottom part is not assible,and told me that they were a bad design,so I did some research and found out about Weber carburators,so I bought one from redline,they cost 269.00 with kit,it's been on my 720 for 6 years now,plus I got a new remanufactured engine from Jasper engines and had a jasper installer put in in at the same time I put the new weber in.I spent a fortune trying to get the stock carb. right.I have 328,000 miles on the truck and it runs perfect.I plan on keeping my truck forever and that's the reason I put alot of money in it,A couple of months ago I redid the interior,it is now gray,was black,I live in Georgia and it is hot.Here's a video of mt Weber conversion,I have more pics and videos in you would like to see.My phone number is 706-580-6110 and my name is Tommy.https://www.youtube.com/watch?v=v5Fe9N0q2Kk

SOURCE: 84 toyota pickup will not idle just happened on

have your TPS sensor looked at since that controls your idle and rpms. It sounds like it's causing your rpms to drop too low

SOURCE: what trans fluid is in 84 nissan pickup manual

No transmission fluid are ever used in manual transmissions.
Gear oils are used. And the specification is:
Gear Oil 80/90W

You would need to park the truck on a level ground in order to do this job.
Remove the filler-plug on the side of the gearbox, and using a hand-pump or a rubber hose, fill the gearbox with the specified oil. Once the gear oil starts to flow out through the side filler-plug, stop! The required quantity is reached.
Replace the filler-plug and start the car to check for leak.
Be careful so you don't accidentally get unwanted item in the bearbox.

84 nissan pickup will not idle down from 3500 rpm


The first thing to do is check the engine for vacuum leaks, use a can or Carb cleaner, spray around the top near the intake gaskets and see if the engine idle changes, if it does you have a leak.

I have 1991 toyota pickup will crank but won't idle


Try this.

Engine stalls cold or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Engine idels at 3000 rpm after replacing carb and vacuume lines with new parts.


There should be an idle speed adjustment screw near where the throttle linkage connects to the carburetor. Turn it CCW a number of turns until the speed drops down. Make sure the choke has completely released before making this adjustment. Hope this helps!
