If you've traced down lots of codes that don't make much sense you might want to get a new ECM, but not before you check all your grounds.

Also, in some situations the module inside the distributor can go flaky and give you certain "windows" in the RPM range where they break up or lose power. Pretty rare, but it can happen.

Any suggestions on how to go about fixing either of those I just replaced the distributer coil and what not so I'm just lost at this point.

Can you elaborate on this?
What all did you mess with in the process?
Pull any vacuum lines or electrical connections? EGR unhooked?

Dwalter191

Well the engine was rebuilt some vacum lines were bypassed before the rebuild and didn't have problems then and there is an egr delete kit All sensors are brand new and all electrical is hooked up.
