I am a 56 year old who's father would only let him drive if I did maintenance on the car, and in 1968 cars did need more work than today. I am an electronics engineer so I will give you my non-professional mechanic but "experienced father" advice.
 
The squirmy-ness may because of the tires having more tread, they could be under inflated, and the worst case would be that they were not installed or were not torqued correctly. Do take the car back to where you got the tires as soon as and as carefully as you can. Sometimes tire cords get damaged during installation and you may need to demand a new tire. Have them double check the installation and then you take them for a test ride before leaving to make sure your car drives as before.
 
I can also tell you from first hand experience that Grand AMs have poorly sealed wheel bearings. When water gets in, the wires for the ABS sensors fail and sometimes un-fail so the lights come and go. This is also a serious problem because your ABS will not work when the lights are ON. You need to go to a service garage with a "Brake System" scanner to determine which wheel or wheels are the problem. I just bought new front bearings for my 2003 GT for about $100 each and you may be able to get installation for $50 to $70.
 
And one last piece of advice that I have given to my three grown daughters - If you are a female, take a male friend with you. All of the professional mechanics that I know are sexist pigs - rude but true.

I only recently saw your request and hopefully you have found a fix for your car not idleing. If not, here are some suggestions: Have a mechanic or maybe yourself, check for vacuum leaks. Too much air (not enough fuel) will cause a gas engine to stumble and stall out. It could be as simple as a pulled-off hose or as serious as a cracked intake manifold gasket.
Ask a friend to keep the car at fast idle, and you may be able to hear the leak - it will "hiss" like a snake. Except for the fuel injection system, this engine is very similar to engines made for the last 40 years. I would suggest finding a mechanic familiar with gasoline powered cars (engines). An experience diesel mechanic may not know what vacuum is - diesels don't generate it.
