Shaking is usually from the engine misfiring. Not necessarily related to the thermostat housing, but could be an indicator the engine needs general servicing. Start by getting the CEL/DTCs read (can be done for free at most parts stores), then address the misfire first. If the thermostat housing is cracked check you have proper coolant levels. Get it replaced soon along with the thermostat.

Scan for the codes instead of guessing. your local auto parts store can do it for free. Post the 4 digit codes back here for more help.

I had that problem, there was a wiring problem with one of the fuel injectors not injecting fuel. I fixed the wiring butt connector and the problem was fixed, of course your problem could be a dirty injector, or a spark problem.
