I have always run lucas injector cleaner and have not had any issues. But I try to put as little as possible in my 08 due to no fuel filter. May try pulling the plugs and making sure they are all good, the plugs last a long time if correct, but when they are done they are really done. Coils are also recommended to be replaced every 100K miles but I told the dealer last time I was in that they could run longer. At 140 now. You have me thinking maybe I should look into this.

LS injectors are also fairly cheap to replace, but it may be cheaper to clean. I have never had mine cleaned.
