86000 actual miles? Mostly, four cylinder--fwd-- automatics--n/a, have no get-up and go. If you have driven this vehicle a long time, then you should notice a loss of power.

Did you check fuel pressure before you replaced anything? Any codes? Do you think the injector might need cleaning? When was the last time it had a tune-up? Compression good in all cylinders? I guess the tranny isn't acting up?
