possible timing problem on 2001 Toyota RAV4

my sister's rav4 suddenly starting running is if it had dropped a cylinder (idoling extremely rough, obvious loss in power) all 4 spark plugs appear fine, fuel injectors are fine, anybody know if somehow the electronic timing could be off and how it can be fixed?
