Dieseling or running-on is a fairly natural consequence of an engine that is idling too fast or being switched off before the idle has been restored after being revved.
Changes to engine design to improve acceleration and economy and meet new emission regulations required higher idle speeds and dieseling became a common problem which required the introduction of a fuel cut-off solenoid on many carburettors.
Dieseling is sometimes the result of overheating or too much carbon in the combustion chamber.
The design changes mentioned above required changes to carburation, including the choke design and operation. Complying with new emission regs required a quick engine warm-up and for the automatic choke to disengage in about two minutes. A higher fast idle was also required and mostly at least one vacuum servo was used to ensure smooth running during the warm-up period.
In order to disengage the choke quickly, it was often arranged to be heated, either by electricity alone or by electricity and hot water.
If the fuse has been removed the choke will not work correctly. Why the previous owner removed the fuse is a mystery, perhaps there is a fault.
The choke must be put back into good operation in order to achieve proper fuel economy and smooth running, or alternatively the carburettor could be converted to manual choke.
the problem may be related to spark plugs,choked fuel filter,dis coil fault if this car is of petrol version.if it is of diesel then chk out diesel filter.injector may choke or improper fitting
stage one tighten 29nm stage two tighten 90-105 degrees stage three tighten 90-105 degrees job done.... hope this helps and if you need any more info/technical data dont hesitate to ask
One problem is related to the other.The dieseling is caused by a rich air/fuel mixture which is caused by the closing choke.So you need to adjust the choke to where it is slightly open when the engine is cold.If it is electric then it has a thermostatic device that positions the choke just cracked open when cold and slowly opens as the engine heats up.Whats happening is the choke may actually be loose and when the engine shuts off the vacuum pulls the choke close creating the combustable rich fuel mixture(if you watched the choke when someone else turns off the engine you'll see the choke flapping while the engine is dieseling).Try putting a screw driver in the carb(with engine running) blocking the choke from closing.Then shut the engine off.It shouldnt diesel.You may have to replace the carb thermostat
Try changing the fuel filter on the truck sounds like it is not getting enough diesel to it. Also check and make sure there is no water in the system. If you have water in the system they make a product that you can put in it to remove the moisture. Can be purchased at any local parts house.
