So, I was leaving my part time job at NTB last night and testing my new Yoko's when I did this again and remembered to ask about it. As I turned out of the parking lot I was in 2nd doing maybe 10 and had the throttle about 75% open and I got a deeper, more throaty sound like my old 3.2 Taurus SHO used to give.

But I only get this sound as the car is warming up to normal operating temp. When at normal temp its not as loud or throaty. Anyone??????

Everything is warming up, thats the basic answer.

I personally hate how the car feels and sounds when it's warming up. I avoid driving it like that at all costs.

The engine runs at a different air/fuel mixture when initially warming up. This is so that the catalytic converter can get up to optimum temperature to work properly much sooner. You're also running in open-loop when warming up, which also has a significant impact on your air/fuel ratio.

That would explain the A/F guage I used to have being so erratic during warmup. Good Answer.
