My question is that my idle at start-up goes up and down for about 10 sec. and then stabilizes-also sporadically at stops the idle will be so rough and at time is smoother, it shakes the car-I have replaced the plugs, wires, coil pack, and replaced a used tested transmission-also the idle control valve is not operating(I took it off the car and there was no spinning evident)-also I have just reset the valve cover gasket and the engine rocker cover still leaks slightly-I secured it very aggressively-could this possibly cause the leak?
