97 sl-1 -

I have a '97 SL1. About 4 months ago, I noticed that the idle was acting strange especially at stoplights where the idle would get so low the car would often kill. Finally, a couple days ago, the coolant light starts blinking on my way to work ( a 3 mile drive). I stopped at a little neighborhood garage to have coolant level checked. Guy says it is plenty full- don't worry. I decided to take it in to the Saturn dealership just in case, for both the light and the idle issue. Dealership replaces fuel pressure regulator, a couple of plug wires and my leaky coolant pressure cap. They also recommend I have fuel injectors cleaned and cooling system flushed, but I am fresh out of money. I drive home and things seem perfect again. Next morning, husband drives car out of garage and as he rounds the first corner from home, all the dash lights lite up like it's going to stall. It doesn't. He gets to work without any other problems. On the way home, he gets about 6 blocks from work and the car just dies. Literally, everything goes dark and shuts down. He coasts to the curb. We have it towed to dealership. When they get it there it starts right up. We asked them to check it anyway. Dealership has had it since Friday- just looked at it today. They say they can't find ANYTHING wrong. Has ANYONE else experienced this? We have had great luck with this car and we are the original owners. We have followed the maintenance guide pretty well and really have had only minimal problems up to this point. What is going on? I would appreciate any advice or info you may have. Thank you.

all the dash lights lite up? what does this mean? Like the ABS light, the Check Engine light, the Oil light, the gas light? which ones? If you really mean all of them then I would say your battery has a bad ground.
