I dought it helps but change the fuel filter and see what it does..................also clear the code and see if it comes back

as far as i know it only happens when my brother turns his chip on but when he is in the stock setting its fine thats all i was able to come up with

Sounds like a faulty box/chip issue. Send it in to Edge and have them take a look at it. Make sure there are good clean connections everywhere, one bent pin can cause all kinds of grief.

My 06 did the same thing, would run rough. When I let it sit for a day it would run fine for a few miles then start missing again. had same code, but when I took it to the dealer they couldn't find the problem untill they finally replaced the injectors and no trouble since.
