Hello,,

Several days ago i went out to start my '95 XJ6, I turned the key and it went rrrrrrr rrrrrr rrrrrrr but would not start, by some miracle, there was a guy next to me with a set of jumper cables so he attached them and it started right up, however, since then it runs rough at idle, if anyone know how to fix it please reply.

 

Flat battery, dying battery, whatever.

Charge your battery, the alternator WILL NOT do it.

These a "juice hungry" cars and rely on a good battery for all the things to work as they should.

Of course something may have gone AWOL, but I doubt it.
