    Adjusted clutch yesterday but the peddle free play adjuster is broken so I had to put clutch back to where it was, could the free play being out of adjust cause my problem?

    You need to check the pedal counts ie; 0 to 100 to see if it,s the sensor or wiring also make sure your idle up on cruise switch is working

    As Worthken stated you can use an analog meter or digital - use duty cycle if you have it or ohms but a dddl or reader would be better - hang ups or small fluctuations are hard to pick with a digital meter

    Im taking truck in for ECM flash in a few months, so if I can't find the fault with multi meter I'll get mechanic to check it out. Thanks mate

    Also when I 1st checked throttle volts , max volts showed 3.9 volts on return wire, is that what it should be ?

    Thats a bit low but either way it will be your sensor playing up or the three wire harness rubbing together
