Hello everyone,
I own a 2004 G35 Coupe that recently hit 110k miles (VIN JNKCV54E74M303078).
My engine recently gave up (crankshaft broke) and a friend that owns a shop is in the process of replacing some of the parts.
Here is the list of parts that were replaced: Crankshaft, Piston, and Rod
We're running into an issue, P0300 random multiple misfires. This happens when the car is in idle or low rpm.
Any hints would be greatly appreciated!
