Stuttering under acceleration *need help quick*
I have a 04 LB7 that is having a problem with stuttering. It happens when i get on the throttle and reach something above 2300 rpm. I first thought it was fuel pressure so I replaced a Fuel pressure regulator (it was putting out a code) This did not fix the problem. I then logged balance rates and found 4 bad injectors. Took it to dealership and they replaced them for me and I still have the problem. I have a P0101 MAF code and a P0089 code for the Regulator. The regulator is because I have a K&N FIPK intake and apparently it doesn't work well with the MAF sensor. I would put the stock intake back on except for the fact that I bought the truck with it and the dealer didn't give me the stock filter housing. What I have noticed today is that right after a full reflash the problem will go away and stay gone aslong as I don't shut the truck off. If i shut the truck down and then restart it my problem comes back and stays there unless i do another reflash. How can I go about troublshooting this? I have to tow a trailer on the 9th and would love to have this resolved before then.
