I guess that means the distributor was never the problem. Check the exhaust for excessive backpressure indicating possible plugged Catalytic Converter.

But the things we replaced were checked out and were bad part. Were replaced think the distributor was tuned to much. Some one else turned not sure which way it was turned. Know that you have no power to run if turned too far one way or shut off the other. The thing is not hitting right. Guess I will have to turn it to get it better trial & error. Thank you if you find any thing send me mail thank you

You have to get the distributor timed correctly before you look any further.

Did you mark the distributor before you took it out or just remove parts while in place-If you took it out and didn't stab it correctly like Mr. Wrench said you need to retime the distibutor-

Remove the o2 sensor and test drive. The power will come back if the exhaust is clogged up.
