try spraying those spark plug wires with WD-40...is a water displacer and will stop the shorting to ground (that you cannot see)~

You may have dirty injectors or the ECM is only grounding those at certain times. First try a bottle of seafoam injector cleaner. The type you pull a vacuum hose off from the intake and put down in the can. See if this works.
