Question: OBD codes , check engine light flashing

I have a 2000 Toyota Sienna. My wife was driving and said the check engine light was flashing and the van was acting as if it had water in the gas. I checked the codes and have 5: PO305,PO420,PO300,PO305again,and PO171. Can you help point me in a direction?

When you've got lots of codes, you've got to come up with a likely hypothesis, and start troubleshooting from there. The p0300 and p0305 codes are for a misfire, which could cause the p0420.

Below are some links that you can read to get familiar with those codes, and see what can cause them and what to test.
