You could have faulty fuel injector or faulty coil. Maybe a problem with wiring circuit, somewhere? Give me a second to look up wiring diagram.

Just to add, how long since a tune-up, spark plugs--spark plug wires, general tune-up. Do you have any misfire problems?

Check your fuel injectors. The ohms spec at 140 degrees F is 11.8--12.6.

You can unplug fuel injectors and ignition model, see if fuse still blows. Does the fuse blow quickly or do you have to drive it around awhile?
