Thanks in advance. I have a 2004 Ford Escape and recently the battery warning light has been flickering on and off. I didn't think much of it until today when it started badly stumbling whenever I brake too hard. The RPMs bottom out and it almost turns off, but doesn't. It doesn't always do this and the light isn't always on, but it's pretty often. Does this seem related? I ask because I recently had to replace all 6 spark plugs and it was stumbling badly before that. It drove great for about 2 weeks before this started so I don't know if its more likely to be related to that, or this new battery issue.
