You may have a stuck injector or as you said a bad coil pack.

You can test injectors with a noid light. Coils can be checked with a multimeter, but it is not very reliable.

If you suspect faulty injectors, and if they never have been checked now would be a good time to get them serviced, they can be cleaned and flow tested, for any ignition problems, normally a run on an oscilloscope will show up any ignition voltage faults, this will pin point a faulty coil easily.
