my gf just bought a 05 wrx that was in an accident, and is getting a misfire on 1 &3 only. rough idle but isnt noticable driving. imma do a compression test, leakdown test and check plugs and coils and also check mechanical timing to see if it jumped. does anyone have any other ideas what it could be?
i was wondering if timing belt jumped how far would it have to jump to bend valves.
