2002 E350 5.4 l stumbles when accelerating

Within the last week my E350 has developed a stumbling problem. The check engine light has not come on and I have checked it with my OBD2 and there have been no codes thrown. I recently changed the fuel filter and I'm wondering if it could possibly be the fuel or the transmission

Stumble at idle? Stumble while accelerating? Stumble at high speed?

Ah, subject says while accelerating. Can you get a fuel pressure gauge on the fuel rail? Does your scanner read fuel trims?

Probably spark plugs, a bad coil will set a code eventually but plugs never will.

True.

Neither will a fuel pump.
