So anyway i'm driving home from work last nite and all of the sudden my truck gets a serious vibe from the motor, more noticable when you step on the gas and the trouble light comes on. so any way i limp it home and plug my Super chips tuner into it and pull 2 codes, PO305/355 (cylinder 5 missfire and coil pak signal failure). So i call around and find a coil pak at my friendly neiborhood parts store, i hop in my gf's POS honda and run down to the store and its the wrong one, same story at all the parts stores in Omaha. It seams that all the parts stores around as well as the internet sites list the coil pak as a Motorcraft DG508. The coil pack i have on my truck has a strait boot and the connector is 180deg out from the mounting ear. The DG508 has an offset (bend) in the boot and the connector is only 120deg out from the ear, they arent the same. has anyone had this prob yet? i called my dealer and they only stocked the 508 and he hasn't gotten back to me yet with any more info.

 

DG508 is a coil for a 4.6/5.4 2V. The Motorcraft number for the 5.4 3V ignition coil is DG511, or 3L3Z-12029-BA.
