I have a 2006 300C SRT8. Preditor tuner, K&N filter inside OEM air box. Nothing special... The last time I drove it (couple of nights ago) the shift points were higher than normal and the shifts were harder. Normal around town driving never went WOT never used auto stick. I parked the car over night on a cold bay area night (30 to 35 degrees F) The next morning I went to start it and it turned over RPMs went up to about 1200-1500 like a normal cold start and then immediately dropped to 0. (Car died out) After three atempts to start it and the same result I switched vehicle to get to my destination. I came home later that day and started several times with the same problem. I held the throttle at 12% and it would stay running. It died out several times through this prosess if I released the throttle. Once the car was warm (Engine temp avove 100F) I could take my foot off the throttle and it would run by its self with the RPMs surging between 400 & 900 RPM. No idiot lights on and nothing on the digital heads up display.... WTF? Anyone else have this problem or heard of it?
PS- Engine oil level is good, and trans fluid is good and does not smell or look burnt.
