Electrical problem
2005 Cadillac CTS Automatic 51900 miles

I had a dead battery that needed to be jumped. On the way to the dealer to replace it, the check engine light flashed on and off. Than suddendly my car when slowing down would jerk, or almost feel like the brakes are locking up. Gradually feels worse until I come to a complete stop. After replacing the battery, for one day, no problems. Today, the same thing happened, check engine light flash on and off, and than the car runs weird. Jerking as i slow down. I have tested the fuel cap, I use good gas, and I have not run over any water. Please help! I have no money to waste on my car. My warranty just went out and I am in need of your help. Thanks a bunch!
