I bought a 2002 Mustang GT 5 speed a couple months ago and have had a misfire at idle and acceleration and bucking under load until 1700 rpm. I have engine codes po161 po720 po141 p1152 p1150 and u1009.
I know what all the codes are for except for U1009, does anyone know what this code is for and how to fix it? Thanks

Your U1009 code is a Loss of signal communications for Class 2 Devices.
Check your radio and ignition wires as well as coils

I am not strong in electrical so please bear with me. Do you know which wires to check? Should I be looking for 12v at the ignition and coils? Thanks
