So I'm in need of some help. My 2001 ford powerstroke 6 speed withe ts 6 position chip was fine yesterday when I parked it. This morning I started it it was running fine but when I went to get on the highway it started sputtering and had a hard time getting up to speed and the check engine light came on.so I took it to the parts store to run the check engine light and it didn't pull up a code said it was fine. Driving it back home it would run smooth at higher Rpms but sputter still at low. I tried taking the. Chip off to see if it was that and it ran the same so any ideas would be grateful. Thanks
