Check engine light codes

Have a '92 bonneville with 3800 engine. Had check engine light read at Auto Zone and codes 41, 43, and 66 came up. Car seems to stumble, bog, or hesitate when you step on the gas and I seem to b using more gas than normal. Unfortunately I've already spent $130.00 on ignition module which I thought was bad after reading fix from auto zone printout. After installing module I had the same voltage readings as I started with. Not sure if cam sensor or something such as pcm would be the problem. Would hate to spend anymore money on parts that I'm not sure will correct the problem. Any ideas? Thanks!
