You could not manually tune in mpfi cars.
the crank shaft or cam shaft.
Above the valve door you have a sensor . its failed reading may cut off fuel supply. I hope its that costly.
Age of car? Normally that sensor do not malfunction that easily , that is build to serve till last. else some one in service center interchanged it with their friends or know car - which happens regularly.
