so far so good, sometimes it feels like it's lagging but it's most likely in my head

i have a 2013 touring,sports package. F.I cat back and k&N air filters. it has 27k miles on it and twice last week when i put the gas to the floor it didn't do anything! it didn't hesitate or sputter in anyway. it was just like i wasn't giving it any gas at all. restarting the car fixes it for now but yesterday my service engine light came on.

You are still within the 3/36k bumper to bumper. Take it to the dealer and have them pull the code.

For me, once I took the car out the dealership, it's never gone back. I had the same thing happen to me, and at around 30K I took apart the throttle bodies and cleaned them, no more problem so far. I also have Uprev cable and I'm able to see which codes it's throwing. If you feel comfortable taking it to the dealer take it

1st, thanks for the info. I do know this: The MAFs are extremely sensitive to dirt/debris. I don't use oiled type filters and have never had this type of problem. What I've learned from this thread is that cleaning or replacing dirty MAFs ain't enough. If the throttle bodies got oily from K&Ns or any other cause, then the TBs need to be cleaned.
