front end on 1990 Oldsmobile 98

After driving for a awhile you come to a complete stop then try to take off the car is very sluggish, What would be causing this?

May just be your spark plug wires. We had the same problem on our 1995 with intermittent rough idle and sluggish take off and ended up just needing a new set of wires. Wished I had known that before taking it to the mechanic. Oh well that is what we pay them for!
