Stutters under load
I have a 2005 f150 FX4 4x4 101,000 miles on it and under acceleration, the engine shutters/stutters between 3,000 and 4,000 RPM’s but settles down when you let out of it or once its above 4,000 RPM. It does it when under hard acceleration from a start or if you gun it on the freeway to pass people. It has never thrown a code though. I have replaced the spark plugs,coil packs,fuel pump and transmission service at 75K. Any help or ideas would be great!

However, there will still be stored pending codes - accessible via an advanced scanner (Mode $06)
BTW - is that WITH or WITHOUT yer Edge programmer canned tuning?

Took the truck to a shop and the tech drove it with a scanner on the passenger seat and no code were found,injectors,coil packs,fuel pressure all were with in range and no misfires were stored. I installed new plugs,packs,maf,intake manifold,FPDM,throttle body,knock sensor all before the fall of last year. I even with to the transmission shop this morning and they thought it was a misfire as well,so what gives? Anyone one else had an issue like this?
