I replace distrubutor without finding tdc. Now it lacks power on the top end of whatever gear it is in. Tried finding tdc so it would start. Got it to start but still now sure what is causing the code. Is my timing a little off. Do I need to try other parts first. Also idles at 20psi on the oil pressure gauge but when driving move to 40.

The code says the crank and cam signals are not in sync. Check the alignment marks below.

The minimum oil pressure, warm engine. Notice these specs are minimum. You could use a mechanical gage in place of oil pressure sending unit, see if same reading.
6psi@1K rpm
18psi@2K
24psi@4K

I can't tell much from here, possibly, not my first thought.
