105 series problem

[Jamesfe]

Hey...hope I can get some clues what to do to get my 1999 105 series landcruiser petrol and gas going properly.
The issue is that when I run on pertol and accelerate from take off without forcing kick down it is very sluggish until it reaches 3,600 RPM then it takes off
Running on gas is performs perfectly from stand take off
So far replaced
6 injectors... fuel filter...spark plugs...fuel pump resistor...
Hopefully some help would be gratefully accepted

Try the 80 or 70 series forum. The 100 series on this forum are mostly NA models with V8's.
But i would check for vaccum leaks as a start.
