    It's not fine.Assuming that the mechanic put in a used engine? could be quite a few things.Does it have new plugs? it could have a bad ignition coil as well.Doubtful that it is the cat converter-that is reacting to problem,shouldn't be a problem on it's own.

    When the check engine light flashes that means the on board computer is detecting a misfire. That is very important that it be taken in and fixed asap. Continued driving with a misfire can damage catalytic converters. If this work is it its warranty period ....the shop that installed the engine (in my opinion) should be correcting the missfire condition. I highly suspect that is what you discribe as shaking.
