Question about 1993 Toyota Land Cruiser
Adjust the TPS to 1-1.25 volts, also u need to test the system for fault codes, (THIS IS VERY VERY IMPORTANT) that might explain the symptom, but based on what you have said i have replaced many engine fuel injection wiring harnesses for just this problem, the symptom is exactly the same, the wire breaks inside the plastic insulator, under certain heat and engine movement conditions the wire breaks connection u get a sever stutter/cough when u hit the gas, can be very intermittent in nature. I have 35 years of automotive electrical repair to daw on here. Also disconnect the EGR valve and see if it has for some reason been commanded to open at the wrong time by the ECM, this to would cause a stumble.
