Hey sorry so long for update. Been real busy with work so event even touched the 350. My buddy with a extra vehicle let me use his truck for the time being. I will be sure to update as soon as I do anything again. Something I can add is that the car is running fine, but a P0420 code came active and won't go away. A guy at work as I could try cleaning my O2 sensors and rechecking. I made sure that all the sensors switch from lean to rich, which they do.

P0300 code at first then goes away.
So I've been reading all over the forums about this issue. I believe it started after a rainy day my car threw me the SES light with VDC off and slip. Problem went away but after a few days of normal driving, my car had, Rough idle and loss of power. Replaced all the spark plugs with NGK platinum and made sure the coil wires were in the correct place. Problem still persists but here's the thing, the car would run perfectly fine after driving for 10 mins or so and come to a stop to let the idle adjust it self. Ive done most of the things other forums said to do so if you guys can help me out that would be awesome. I have a 2003 performance model. THX
