the intake maniford tuning imt valve is stuck open how do i fix the problem
It's a valve in the intake manifold that controls airflow depending on RPM, for maximizing volumetric efficiency at both high and low RPM. Many design parameters of any engine are chosen to maximize either low end torque, or high end horsepower, or most often, some sort of compromise between the two. The IMT Valve helps make it possible to design an engine where both are better than if it didn't have one. Variable valve timing operates on much the same principle, except this applies to the air passages in the Intake Manifold. How you fix it would depend on why it's stuck open. But I wouldn't count on a cleaning being able to fix it. More likely some sort of physical or electrical problem. Either way, chances are you'll need a new one.
