Were the coil packs changed when the HKS plugs got replaced for the OEM plugs? I don't imagine the injectors are bad but anything could be possible. I put a whole bottle of SI-1 Redline Complete Fuel System Cleaner in my tank every 3k miles to try to keep it injectors clean.Update : Finally got the car back. Driving home cruising and cel pops up. Call dealership and I drive back. They inspect the codes and it was a slight misfire he stated. The tech is not sure of the cause. Driving back home again and the cel pops up . Once home cut the car off and five minutes later turn it on and the cel is gone. Tech told me to monitor it and they will handle anything that needs to be done whether coil pack, plugs, or injectors but they did not find anything. Definitely will keep a close eye out on this. Praying for some good luck finally with the vehicle. Intakes and custom exhaust is all I have mod wise and will continue to have . Don’t want to add the jb4 until I know the car is running good and healthy . I believed I asked this question before but is there something wrong with plugs/cylinders on stingers as a whole ?
You can try emptying a bottle into the tank when nearly empty, if a fuel treatment hasn't been preformed in a while.
