I have an '77 FJ40 2F motor and have a question about delayed power. The rig is warm (happens when cold but choke is out and helps hide the trouble) and I start off the line and gradually depress the gas pedal. About half way to fully depressed there is certain number of degrees of depressing the pedal that does not change the acceleration at all it does not lose power either but remains as if I was not continuing to depress teh pedal but I am. Then I get past this spot and it accelerates very well up to full throttle. Does anyone know what might cause this apparent dead spot in the acceleration process?
