MY HAS A VERY ROUGH IDOL, WHAT SHOULD I DO?

1998 Oldsmobile 88 • 136,922 miles

I have a delta 88 Oldsmobile that I just replaced the battery and all the plugs and wires, but the idol is still rough like there's a dead cylinder or two, it shakes the entire car and I have to press down on the gas pedal in order to even keep it RUNNING! What should I do/check?

Is the Malfunction Indicator Light showing and have you checked for trouble codes?
Any difference before and after replacement of the parts conerned?
