it was running kind of rough that week the timing jumped. Would it the map sensor or a vacuum hose to the map sensor?

And no it didn't do that before the timing chain was replaced. But on my car the timing is set by a computer.

The ignition timing is controlled by the computer, not the valve timing. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

I had the codes checked and it gave a MAP sensor code.
