ok let me see i can hear what you are all talking about..
so what did you think about the sound of my car?? can not wait to get a cam

yep very deep in person

ehh i still like it

Verdad Gallardo Our definition of cold start isn't the same though...since you started it up and moved it 10 feet, and took a phone call for 5 minutes, that still makes it not a cold start in my books. The PCM has counters in it from when you turned it off that don't go away for quite a while (although I don't know how long they last off the top of my head, but I think it is more than 5 minutes), and that changes startup behavior (making it purr to life instead of barking).
I think I've whored up your thread enough. I'll ***** it up some more tomorrow when I get a video clip of my own to elaborate on this
