I have a 94 Olds Royal 3.8
I have owned it about a mounth.
When I bought it I thought that the engine "shuttered" a little at about 40mph.
Now the enging shutters worse and it dies (sometimes) when I let off the gas.
Idles acclerates good.
I took it to a shop to be analized. They said "spark knock".
They said to change plugs & wires If that dosen't help, have injectors cleaned. I changed plugs & wires. I also filled the tank with "HI-Test" and carb cleaner. = NO GOOD
Help

Check for spark at each plug, coil packs sometimes do go bad, take a look in the towers that the plug wires plug into, any corrosion? rust? if so replace it, Does it seem to be misfiring? Is your check engine light on?
