F430 resonance at ~2500rpm when cold
I recently bought an used F430 F1 Coupe. It's brilliant, but wanted to know if this is a feature or a problem:
When the engine is cold, there's a fairly strong resonance/rattle at around 2450-2550 rpm, regardless of the gear you are in.
The car has a standard exhaust and the exhaust fastening bolts have been checked to be OK by the dealer. I have been told it's because of the rigid frame of the car, but wanted to hear if anyone else has a similar experience with their F430.
Other than that the engine sounds perfect, but this makes it sound like one guy in the orchestra doesn't play according to the notes...
