SOURCE: Nissan Terrano Chugging
When you are going up a hill, the engine is under an incresed load - requiring more fuel and spark, so I'd first check all of the ignition related items (Plugs/wires/cap/rotor), and it isn't a bad idea to replace the fuel and air filters if you haven't in a while. Once those are checked, it is very very common for a TPS (Throttle Position switch) to develop "dead spots"; where under accelleration they cause a "chugging", which sometimes is quite unnoticable - unless/until vehicle is under a load ( eg. driving up a hill). A new TPS can be installed and set with a multi-meter - probes attached to the proper terminals, and have the output voltage set at .47V to .50 V at idle (Closed throttle). I'd bet this is the cause, as they usually do not set a DTC (Code - Service Engine light) . It isn't 100% for sure, an air flow meter and/or other things can cause this type thing as well (also a weak spark or coil, etc), but highly unlikely - other malfunctioning parts often set trouble codes as well, and usually either malfunction or they don't. Hope this helps and if you find anything else - please let me know.

well there are a few reasons that could cause this problem some of which are easy fix others are a major fix.
1)The throtle valve cable could be out of adjustment, for this to be corrected it is best to be taken to a transmission shop, or you could buy a Chilton or Haynes repair manual to see how to adjust it yourself.
2)The O.D. solenoid (which depending on the transmission in the truck) is either inside or on the outside of transmission, could have a bad wire going down to it, or have a bad connection to it, or it may not any power getting to it /// First Check All Fueses on vehicle then locate where solenoid is the check wires for power. The solenoid could also be plugged or bad depending on condition of trans and the ATF.
3)In side the transmission the is whats called a Over Drive Clutch Pack and the cluthes could be worn out or completely gone this happens quite often with older vehicles. If this happens to be the problem then the only possible fix would be what is called a OVER HAUL in which the transmission is removed from the vehicle, disassembled, all clutches and damaged parts in side are replaced, then transmission is or should be cleaned and then reassembled and then the transmission is reinstalled back into the vehicle.
So depending on where you live there might be a transmission shop that might diagnose the exact problem of your 93 nissan and give you a quote on fixing it. Some shops do this for free other do not. My shop does this for free. So I hope this helps you with your truck.
