I bought a 2008 F250 w/ the 6.4 about 1 month ago. Over the last couple of weeks I have began to notice a hesitation under light acceleration between 1800 - 2000 RPMs. To me it seemed fuel related to I removed and cleaned the hfcm and replaced both filters. Same result.
I do not notice the issue when the truck is cold or when you accelerate at a faster than normal pace. The check engine light is NOT on, there is no smoke, and it seems to run fine as long as you accelerate fairly hard. It will run on the highway 80mph + with no issues, but due to this problem I have only driven it to test. Just looking for some things to look for.
The truck is tuned w/ a SCT tuner, has a DPF delete, but the EGR is still in tact. Planning an EGR delete and different tuner soon, but would like to get the issue addressed. Any input would be appreciated.
