Car cuts out, anti-lock light

[b00stedtalon2]

I went to start my car this morning ( 91 TSi AWD) and it seemed as it had no power. I jumped the car and it then started up. As soon as I put it in first and started driving, the car starts to cut out every 3 seconds than starts going again, makes driving the car feel like I'm driving over a rocky mountain with the car jerking back and forth as it cuts out every time. The anti-lock light is flashing as this is happening.

Any idea's? I checked out all my battery cables and everything is nice and tightened.

Have your alternator tested. Common signs of a failing alternator include dash indicator lights flashing.

any other electrical problems? like windows not working and gauges acting up also? If so try the Fusable Link.

You could possibly have a dead alternator or battery, as stated above. Have them tested/changed as necessary.

im having this same exact problem now. i just replaced the battery yesterday and it started happening again today. so since my alternator is on a lifetime warranty, im gonna change that again and see what happens... hopefully, it was just a defective alternator.
