Pull the battery cables for a few minutes. Reconnect and it'll be fine. Its the 05 MDS issue.
RE: 2005 MAgnum Predator making car run rough
Which battery?
RE: 2005 MAgnum Predator making car run rough
Theres only one. The cars battery. Its in the trunk.

I've seen some instances on the '05s where they crank up in MDS mode. Do you have a quick adjust option to disable MDS to see if that makes a difference?
RE: 2005 MAgnum Predator making car run rough
I disabled MDS and runs smooth as ever. Thanks for all your help.
