Gm fellow cadillac family members. Im in desperate need of your help. About a week ago on my way home my car starts trembling, shaking and lost power out of nowhere. Never experienced this problem before. The following day i got the codes pulled. Says im having misfires would need a general tune up.

Called my mechanic shop. told him what the problem was. He said he would check it out. So i got my car towed there.The next day i received a call from him saying my catalytic converter was clogged bad, and thats a 90% chance thats causing the misfires. Got the converter changed with a gm direct fit converter. He called again saying the car is now misfiring on three cylinders the same side the converter was changed and that i would now need a tune up. I gave him the ok to do it. Called the next day. Said he changed all spark plugs, three ignition coil packs on the cylinders that was misfiring Camshaft position sensor and some other part that had to be piggy backed along with it. He says Im still having misfires and dont know y suggest i replace the engine. So now im waiting on a price for an engine.which i know i probably cant afford at the moment. So ill be getting the car towed and getting a second opinion from somewhere else. Has anyone had this problem before or know what can still cause missfire after the work that has been done? Did he miss anything? Additional info. Cts v6 3.6 107,000 on the clock. Had fuel filter changed about two months ago. Only use shell and exxon gas. The day before i got it towed to the shop I Cleaned the throttle body. Car was on E put a bottle on techron fuel system cleaner and fresh gas. The same day i experienced the misfires i had my transmission fluid changed along with new filter and gasket. New brakes,rotors and clipers in the front. Pls any input would help. Thanx
