2003 Econoline 4x4 E350

[dusty22]

[color=darkslateblue][font=arial black][size=4][b]Having problems with 2003 Econoline E350, diesel, 7.3 liter... Starts without a problem but no accelerating. Check throttle module and it seems to read on the ohm meter. The question is what is the two wire connection next to it? Or is it a problem with the throttle module? I give up, any help would greatly be appreciated. Screw the icons... Need help!!!
