Your thermostat needs to be changed. That is what makes your vehicle get hot. You may also have a vapor lock as well. On top of the thermostat housing there is a little bolt that works like a bleader screw on the breaks. In order to make sure that it is not vapor locked you will have to start the vehicle and loosen the bolt just a little bit until antifreeze or air starts coming out. If there is air then you'll need to leave it loose until all the air is out of it once you have a steady stream of antifreeze coming out tighten the screw up. That should solve the over heating problem
The check engine light flashing is a pretty much universal sign that you have a misfire that is bad enough that a lot of raw, unburned fuel is being dumped in to the Catalytic Converter, to the point that it could be ruined if the problem is not taken care of very quickly.

Very possibly you have a bad motor mount. Is the engine missing or running smooth but shaky? If it is missing, then it may be plugs, wires, or injectors, if runs fine but shaky, then you may have a bad motor mount.
Or the timing chain or belt. Not sure what year we're dealing with. Shoot a timing light at the crank. If the mark isn't staying in one position, you have a timing belt issue, and it will have to be replaced. Could be a valve or the cam, too.
the engine mounts and the transmission mounts are broken which causes vibration you can test this by slightly lifting the engine a little bit using a small floor jack but do not lift too much on the oil pan just enough to raise the engine a little and you will notice the vibration is gone if this is the case replace all the mounts.
