Mighty Shilling

Alrighty. here's the deal. my car was stuttering a while back if you can remember. so I replaced the DME relay like I was told. Also, I have got a temp gauge issue where sometimes it reads way too hot...but it isn't cuz it bounces around when it gets up there. It seems to happen mostly on cold days. Anyway, despite the DME replacement, it's still stuttering. and I've noticed that the temp gauge and stuttering happen approximately the same time. this disturbs me. I'm not a whiz with electrical work, so I'm debating on whether or not to ship my car off to my Porsche tech, but I figure I'll check it out here, and i'm not gonna ship it off till after spring break. I need "Porschephile is gettin Hammered in Florida" money. So, Any coloradoans willing and able to come out and help for a case of beer? any suggestions? or should I just take it to my tech?
