I have had this issue since the HPFP recall, but it has never gotten close to stalling, just rough idle 600 to 700rpm
5 injectors were replaced under recall at the same time.
No change in fuel econ.
Spark plugs were changed recently, NO CHANGE AT ALL, not worse or better
question for those of you that had this problem after plugs were replaced:
if you replaced the plugs yourself, did you use dielectric grease on the coil terminal prior to reinstalling the terminal?
did you use any kind of antisieze on the plug threads?
