The info above is approx. Your recall of gm cars with to ignition problems may not be broad enough. I traded in my 95 Riviera in April of 2007 after plowing $1500 into and still no satisfactory repair on why it was stalling. The last stall was in a three way intersection in chicago. Each time it stalled I lost power steering. I don't recall if the dealer looked at ignition issues. I do recall that they were at one point focused on the carbeurator. It was being serviced by a dealer in schaumberg, ill. Sorry I don't have better recall of details. Once I traded the car, I tossed the documentation. The last stall was scary and the reason I traded the car.
