Friend has an 85 PA, 3800 with a distributor. It dies sometimes and doesn't idle smooth. Needs jumped to restart sometimes. The injectors are loud to me but may be normal. Service engine soon light works but there are no codes. Alt. tested fine. Did notice the battery had a site window and didn't have the green bubble in it. If the battery was low could it still cause the engine to run rough? Any help would be great, thanks!

Sounds like ti's just fllat out neglected. OPoor battery condition, probably needs a tune and EFI attention.

Will let him know, thanks.
