No. 7 coil still showing problem, Have repace it, still having a misfire. Code read 300 and p300. Dealer stated they have to tear down engine to find out problem. Is this true? The vehicle is not making noise.

Try checking the compression, injector and sparkplug for that cylinder

Are you sure it is the #7 cylinder? A PO300 is a random misfire. Have you done the things that the last tech has recommended? As far as tearing down the engine, usually a mechanic can get a good idea what the problem is by doing some general testing that doesn't require the engine to be taken apart.
