The trouble code P0352 in your 1999 Ford Mustang is related to the ignition coil system, specifically, "Ignition Coil B Primary/Secondary Circuit Malfunction.
I would swap out the ignition coil which can cause this code and make the engine run badly. Check out the images (below). Please let us know if you need anything else to get the problem fixed.
