lugs nuts came in




Also I was having a driveability issue with the car. Engine was randomly stalling when coming to a stop. As revs fell back to idle, they would drop below normal and then stabilize. Idle was rough with unstable rpms. And there was a very high pitch whistle like noise from the engine bay. Took me a while to figure it out but it was a simple fix...BOVs weren't fully closing at idle, low rpms and decel due to a soft spring (softened with time). The gap was very small causing this whistling sound as air rushed out. I added a couple of flat 16GA 1" ID machine bushings to the bottom of each BOV housing effectively making the spring stiffer. Problem solved! Car drives perfect now.




Tires come in next week.
