Hot restart misfire

Hello,

This sounds like an engine coolant temperature sensor is going out, but to be sure lets run the codes by following this guide.

Please run down these guides and report back.

Cheers, Ken

Codes are P0300, p0303, p0302 and sometimes p0301. I also noticed on the scan tool that when you start the engine while is warm it goes to open loop fault and the O2S11 is reading negative or only goes up to 0.0002. When it goes into open loop fault that is when the check engine light starts flashing. Thank you

I have seen oxygen sensor short out causing the problem you have described. Let's disconnect the sensor and drive the car to see if check engine light acts the same.

Here is a guide and diagrams below to show the oxygen sensor location:
