    Once Start it's at full throttle.

    Haven't play with my 4 tec for about a week. Got it started yesterday but It was accelerating at full speed with out giving gas. Every thing work fine a week ago.

    Could it be a fail Carburetor?

    Check to make sure the idle gap is at 0.7-1.0mm open. The only way it goes to full throttle is when the carb is opened fully.

    With it NOT RUNNING, remove the air filter assy, look down into the carb, turn it all on, pull the throttle. it should open and close. +1 on checking gap.

    This is a beginer question.... and that is NOT a begginer car LOL

    Maybe batteries are running low on the car itself.
