May need to re-learn the crank sensor signal. You need a factory scan tool to perform this procedure. Correct spark plugs are improtant and the gap should be correct. Some bubbles in coolant could be normal if you are not loseing coolant or not overheating. If it is running rough I would try and disable spark to each cylinder one at a time to see if one of the cylinders is not contributing thus could mean a mechanical , fuel injection problem or an weak spark to a cylinder. - milesauto
