I would start looking for air leaks. This could be under the throttle body, the injector mounts, air bleed screws or excessively worn throttle plates/bores.

Have you verified that all throttle plates are closing down fully?

I would take off the throttle bodies and look at them behind a light. Does there appear to be much wear? Open the butterflies and feel for ridges or open spots. Do the throttle shafts have play?

If you know your timing is correct and you know that you are not running really lean you need to look further.
