The 2001 Oldsmobile Aurora originally came with either a 4.0L V8 engine or a 4.6L V8 engine, both of which are specific to the Aurora model. If you're looking for a compatible replacement, it's best to source an engine from another 2001 Aurora or from a similar model within the same generation (1995-2003). Additionally, you might consider the 4.0L engine from the Cadillac Seville, as it shares similar components. Always ensure compatibility with your vehicle's transmission and electronics when considering an engine swap.

Have your Torque Converter/ Lockout Swith checked. I would also be worth it to have cam timing sensor checked. I had this exact problem on my 01 Aurora V8. Replaced sensor. Haven't had a problem since.
