Hilux - accelerator cuts out

[Hiluxdap]

Toyota Hilux 2001 farm ute accelerator cuts out at 1500
revs. Replaced accelerator sensor and at
a loss. Would appreciate any assistance!

define cuts out pls. does it run ok for a while the stop, or does it peter out? does it suddenly cut out? I'm suspecting a blocked fuel filter or similar. Remove it, estimate weight. They shouldn't be heavy. Has it water in fuel? Or algae?

Sorry the Hilux will idle it just only reaches 1500 revs - the motor doesn't cut out. It just won't go above 1500 revs. We have tried the fuel filter/dirty fuel. Thank you

You have efi? check for fault indicator code. Does your throttle system have full mechanical travel from idle to max power? Does your throttle position sensor have full travel with the cable movement? Is it and its' connections clean and dry? Does the exhaust go black on full throttle at limited rpm? Does moter get too hot if worked? Verify clear air inlet passage/clean air filter. Verify fuel pressure, clean/test injectors, There should be an in- tank filter-check it. Has the motor been sitting unused for a period? are all cylinders firing? How much fuel is being returned to the tank from the injectors? Is it nearly due for a cam belt? Has the timing belt slipped? Check rpm sensor. Vertify clear, undamaged exhaust. Blocked pipes/mufflers do bad things.
