Hello all, I've been having some issues with my 2003 GT. Every once and a while (rarely, days apart when i notice) the rpm will go down under 600rpm upon braking and very rarely while idling. It has died on me before while driving about a month ago, but i was having electrical issues at the time and all was well for a little before last light. I was driving home and when i went to stop from a 40 roll (auto tranny) under deceleration the rpm dropped as usual but it kept dropping all the way to about 200rpm and then it went back to normal. I saw this immediately and tried to replicate it on a straight road right beside my house as i was almost home, and it did it again. I drove maybe a half mile and got to my house and parked it. I didn't turn it off yet and heard a odd sound coming from my motor. It wasn't mechanical sounding it was more of a deep bass note. I then gave it a quick blip of the throttle (1500 rpm max) and the rpms went up and then down normal speed but it didn't stop at idle and kept going to 0 and the car died. I then tried to crank again, it instantly fired up and then died. I knew something was definitely up then so i checked my gauges and my oil one is far far to the left. it doesn't even get in the range as its suppose to. I cycled the ignition to off and back on and all the other gauges are normal but the oil one still barely moves and is not even to the minimum bar. I know its a dummy gauge but that still cant be good. I had to work at 8am the next morning so i went in and haven't looked at it since. Any help would be greatly appreciated..
