    get this... throttle servo is working and brakes do work, but when i start truck, it just goe full throttle.. i can steer but can't control throttle and brakes are useless.. what should i look at? the throttle is responding when the truck isn't running. lol.. when i start it..the truck just goes and the the engine revs up and goes..what do i need to look at?

    are you sure your idle isn't just set to high?

    your throttle trim is set to high......

    ok, turn the cars electronics on, but dont start the engine...... pull off the air filter and check the carbs opening.......when the trigger is NOT being pulled, it should hace like a 1.5 mm gap.

    Its real easy to inadvertently hit that trim dial while running or between runs.....so my be is the throttle trim......as was stated above.
