Hilux surl: . My Toyota hilux surf won't rev up fully, sometime

Customer Question

Hi. My Toyota hilux surf won't rev up fully, sometimes not over 1500 sometimes 3000 revs but makes a difference when I turn engine off and turn it back on again sometimes it will rev to full revs but slowly run down again as I drive? I think this problem is like a sensor or an electrical problem but what I don't know. Can you help do you know what this is?
Ps I have changed the fuel filter and cleared fuel lines. But can't be blockage because sometimes it's reving high and sometimes not, depending if i just turn off and turn on again!!
