Try your coil packs. May be a cylinder misfire on either cylinder. If you changed any cylinder, and still getting no fire, the coil pack May be good, the module May be bad. Also check for broken or loose wires. Hope this helps.

Reginald, my Lucerne is riding rough, what could it be.

Reginald Walters

Have you had an alignment, or rotated your tires? That may be a start. Also try driving with the traction control on. If all else fails, could be as simple as a warped rotor.
