Re: 97/98 2.5 petrol Sport - lumpy running

What all was done in the full service? My first thought would be to replace the distributor cap and rotor, as well as plugs and wires.

It sounds like you have a miss condition under heavy load/low rpms, such as chugging up a hill. Which is usually an ignition issue.
