03 F-350 7.3 over accelerating probem?

I have an 03 F-350 7.3 with no tunes or mods, no cat and straight pipe, I do use eff bomb fuel additive each fill up, 200k on the odom, I use full synthetic oil. I just put in a new fuel filter too. About 2 months ago after I filled it up I got about a block away and went to leave a stop sign I pressed the go pedal like normal and the truck spun the tires leaving the stop sign. It only over accelerated for about 50 ft or so then check engine light came on, the light went off about a mile down the road. After that it would usually only do it after I drove around for a bit, park for about 20 minutes get back in the truck and it would over accelerate. This would happen maybe once a week. Today it was doing it after I sat idle at a stop light for more than a minute or so then holy hell, off she went, every stop light. the check engine light only came on 2 or 3 times and its over accelerated more than 20 times. Any thoughts?

Mine did that several times. But only for a second or two leaving a stop light. I had codes relating to the Idle validation switch and accelerator position switch. It stopped that little trick and has not done it in months. What codes do you have?
