Thanks for the suggestions. Ferrari of Washington put in a new oil pressure sending unit and that did the trick. No big deal but it did cost about $800 to install. They also had to replace the front right wheel bearing which was making a noticeably loud noise (like a pickup with big tires) going around turns. The also had to replace one of the bulbs in the headlamps. All told I ended up sinking $2,138 into the car for stuff that Lamborghini of Atlanta missed during the PPI. How you miss a flashing oil pressure warning light, a burnt out headlight and a wheel bearing that is humming like the tires on a Mack truck during a PPI is beyond me. Enuff said.
