Hi there sorry if i have done something wrong but im new here and to a hilux! I have a 3.0td surf 1996 and having a few teathing problems.... its a auto and if i put my foot down it cough and splutters. The other day it even cut out whilest going along. It also seems to be alot worse when going up a small hill.

 

could be a number of things. but if it bucks and jerks going up a slight incline hill under normal driving, that sounds like an ignition misfire. take a look at the plugs, wires, and cap/rotor. if you are unsure of the last tune up, wouldn't hurt to go ahead and replace all of those.

 

i think he has a diesel...
i would check your fuel filter first off..
most ppl are here has gas toyotas

 

Possibly the injection pump. But start with the filter.

 

yeah i'd still check the cap/rotor and plugs and wires...............................

 

Either your trying to be funny or don't know your way around a Diesel engine.
Make sure there isn't any water in the fuel, I second the others, start with the fuel filter

 

sarcasm is hard to express over the internet. i saw 3.0 and assumed gas engine.

fuel filter would be a cheap place to start, and its a maintenance item anyways. not sure how to test for a bad injection pump. i do know from farm tractors that injectors can clog over time and need to be rebuilt. i take those injectors to a diesel injection specialty shop and they can check the spray pattern and check for leaks, and they can rebuilt them as necessary

 

also, another common thing i see is dirt in the fuel lines from the pump to each injector. i'll remove each line one by one and blow them out with air. usually there is a constant miss when this happens though.
