Can you provide the exact codes that you are getting so that we know which cylinders are misfiring? Then we need to review this guide because there are a number of other things that can cause a misfire.
The flashing engine light means that there is potential damage being done to the exhaust and engine systems as a result of the misfire so we don't want to drive the vehicle until we figure this out.
Lastly, when you say there is a coolant leak, is that an external leak or are you loosing coolant and have no external leaks?
We are going to need to get more info from here in order to figure this out however, let's start with this and we can determine next steps. Thanks
