I have only had the normal problems that all Aurora owner face... the fuel gauge sending unit gets corroded after a few years and gives false readings. It's a $20.00 fix, just haven't got around to it yet.
This is without a doubt the most sophisticated car ever made by Oldsmobile in their 105 year history. Only 189,291 of these cars were produced, with a price tag exceeding $40,000. These cars are nothing short of a Cadillac, they share the same transmission, electronics and engine. The Aurora engine or L47 is the Northstar 4.6 in smaller displacement. They have the same intake, exhaust, lower bearings, heads, connecting rods, cams, etc.
I have been customizing mine for 4 years now, I have a 900 CFM true cold air intake with heat shielding, MSD ignition & Edelbrock custom cat back exhaust. I also switched to 255/55 R 16 tires over the OEM 235/65/ R16. I am pushing pushing 290 hp and 300 ft lb torque.
Have you run it at a dragstrip to see if it is in fact putting out 290 HP?
