Chevrolet Repair: cavaliers, start something, sherry

Question
I have a 1999 cavalier. I turned on my car today and drove about a half of a mile and the car started to shake. The whole car was shaking like I had a flat or loose tire,but it wasn't the tires. I pulled over waited a few minutes and started to drive again. this time it was fine. what do you think this could be?

Answer
Hi Sherry,
I think that during the first start, something didn't get read correctly by the computer, and it wasn't working with good information from the sensors.
You did the right thing by shutting it off. Kinda like rebooting your computer when things aren't working correctly.
If it becomes a regular thing, take it to someone who can read the stored codes.
