i know the aa and tthe ac are for differnet types of injectors. then i unplugged the boorowed one and compared the 2 numbers and this is the original one that was on the truck IDM-100 f6tf-12B599-AA and the borrowed one is IDM-120 XC3F-12B599-AC. it idle beautifully start up right away but no balls on the fuel pedal. then i tried a different idm someone let me borrow. so i then changed my old vavle cover gaskets and plugs with wires it needed it but didnt solve the problem then i changed the icp sensor it wasnt thats so i switched it back and was able to exchange back that was the most expensive sensor i ever paid for.
