Long story to get to the point...

98 XJ w/200k all stock. I bought this ride about a year ago and it's been pretty trouble free. It has always had a stutter under load at lower rpms but I've just dealt with it. In the right situation I can even get it to backfire through the intake. I do know the exhaust manifold is cracked, but so has every other XJ I've owned and never affected anything.

Last week I took of down the street and it wouldn't get out of its own way. It was backfiring through the intake and the alt gauge wasn't working. Now the damn thing won't sit and idle. I checked the battery and it has 12v but alt died not seem to be putting out any voltage when checked.

Does this sound like symptoms of a bad alt or voltage regulator or are the problems not linked?
 
Put a new alt and battery and its back to business! Still have the original stutter during low rpm high torque operation, but I will sort that out next.
