I'm an electronics engineer with lots of automotive experience and the connections are usually pretty reliable, but it would be pretty easy for a mechanic to check for broken or pulled wires. (my car is a 2003 Grand AM GT) The wheel speed sensors for Grand Am's are poorly sealed from water. At less than 60K both of my front wheel sensors failed, and now at 64,000 miles, the rears are going bad and causing the same ABS and Trac Off lights to come on. Mine are failing with a bad internal connection, so the lights come and go. A $300 ABS code reader is needed to diagnose brake problems. It is important to get fixed as your ABS will not work while these sensors are bad.

Less than a week ago my service engine soon light came on in my 2000 Grand Am SE. It was running fine, but I still brought it in and the diagnostics said that it was my evaporation emission system (something like that...). The mechanic said it was "out of wack" and it just needed to be reset. He did this and my light went off. Now today (less than a week later) my service engine soon, abs,and trac off lights came on. My car is still running fine. I am in a carpool and the lights came on right as we were about to leave from our meeting spot, so someone else drove. When turning my car on to come home, I noticed the lights were off. I am not sure if my last week occurrence is linked to this someway, or if they are just a coincidence. I just got 4 new tires 2 weeks ago and am not sure if that is linked somehow as well? Ever since I got new tires my car drives like it is windy outside (even though most of the time there is no wind at all). I am a very paranoid person, so this part may be nothing at all (or maybe even my imagination...not sure.). I am a 22 year old who doesn't know anything about cars. Is is even safe to drive?!? I drive an hour to my teaching job everyday and do not want to drive it if there is a chance it might brake down or anything.

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.

2001 Grand Am SE, 3.4L. These 3 lights come up on my dash, no codes in computer, not pulsing/pulling when I brake and the first 2 do not come up if I ti=urn the trac control off when I start the car. Is my ABS connection loose at the hub? I just had them both changed last May and June of 09
