I'm having a problem with the mystique (mtx) that might be called a st..st..stutter, although I would call it a sh..sh..shudder. It occurs when I am accelerating, under load. The front end has new driveaxles, struts, balljoints, front and rear motor mounts. For what it's worth, the problem is less noticeable when the tires are over-inflated (36-40psi). Also, the problem seems less noticeable when the fuel tank is nearly empty. I know my front rotors are warped, and I know the rear control arms are bent. I first noticed the problem after I hit a bump in the road.
