Naveed,
I always try to be helpful to you. So that is why I wrote
"The proper calibration settings are available in the factory service manual. If you have mislaid the link to the FSM..." in my first reply to you.
I wrote out Factory Service Manual, I accept I did not put these in Capital Letters, then I wrote FSM. FSM = Factory Service Manual.
Yes, you have downloaded the correct manual from my site. I spent considerable time taking the manual I found elsewhere on the internet and running it through Adobe software so that search functions work on this document. A search using your PDF (Portable Document Format) reader would have found reference to the Fuel System. In fact, if you go to the document index and click on the heading Fuel System, it will take you right there. From there you will see the Fuel System index and locate the instruction to do with the Injection Pump. They are on page FU29
Naveed, this is the Factory Service Manual. It contains all the
information a competent repair
shop needs to get your pump running correctly.
I SERIOUSLY AND SIGNIFICANTLY URGE YOU to NOT let anyone tinker with the insides of your injection pump. These pumps are renowned to last a very very very long time without tinkering inside them. There are four adjustments on the outside that you can play with if you are really confident and can return the settings to standard should you wish.
The first, and I suspect what your problem is, is the idle speed adjustment. This is a simple adjustment near where the accelerator cable joins the injection pump. I think your lumpy idle is from the idle speed being too low.
If you increase your idle speed to over the factory standard setting and you still have a very lumpy idle, then someone has stuffed up your governor settings. A competent injection pump
shop with a proper
test equipment will be able to reset the pump when it is OFF the vehicle. If there is no competent injection
shop in your region, you will need to find someone in your own country or post it to a place in Australia for recalibrating.
There is also an adjustment in the same area that controls the idle speed when your air conditioner is turned on, or when the vehicle is cold. Simple adjustments.
The other two adjustments are your maximum fuel setting, and your off boost fuel setting which controls the fuel as you initially accelerate. I am not going to go into this here, but have covered it at www.peoplehelp.com.au/landcruiser.
Most of the time NONE of these things need touching. If you have tinkered,
well.... it's going to be hard to help you.
I've also suggested that the level of technical expertise in this
forum is sadly pretty limited and you are better off at I8HMUD.com or
http://www.outerlimits4x4.com forums for tech support.
I trust this is useful
feedback.
