Engine Performance problem
1990 Oldsmobile Cutlass 6 cyl Two Wheel Drive Automatic 132,OO miles
----------------------------------------------------------------
After driving for about an hour, it starts to sputter and then dies. It starts up an runs great, as soon as ii put it into gear it dies again, so i let it cool down, then it starts. I can go back and forth with this. It has a new computer put in it and it tested good.
