Friday morning I got in my truck to start it and let it warm up a bit. It's a 03 6.0 CC 4x4 Auto. I have an SCT and had a high HP tune in. The temp was about 25-27. I have ran this tune all winter with no problems. I am currently running synthetic Rotella. I cranked on it about 4 or 5 times and it would turn over and sound like a high idle for about half a second and then die. It did this every time. I cut the switch off and patted the go pedal 2 or 3 times and it started. When it started, the engine emissions light came on. When I left the house I was going along normal and it would rev up by itself without giving it any gas. Sounded like it does when it flare shifts. I drove it for about 5 miles and it did it every little bit. I stopped and took the tune out and returned it to stock. I also cleared the DTC. Even on stock it still did it. It revs itself up. Doesn't matter if you're stopped or not. Seems to just do it when I am giving it very little gas or no gas at all. It does it while idling also. What could cause this. Never had any problems with it before. Thanks.
