1992 Saab Turbo convertible. Starts and drives beautifully, 90 percent of the time. At times the car will randomly not start and makes no sound at all, when you jump it it normally starts right up but not always, as a matter of fact sometimes when you just let it sit it starts right up.(Not for nothing but the brake light and a few others stay lit for a short time while driving)
Just to make this more fun every once in a while it will just stall while driving and then will not start.
Replaced so far Battery, starter, alternator, plugs, ignition switch any ideas?
I am losing hundreds of dollars gambling with my wife on whether it will start or stall. I am laying 90 to make 10.
