..... and if that isn't the problem (MAF), give the old negative battery terminal disconnect for 5 minutes trick a try. If you have a code reader handy for the OBDII port, see if it will pull any codes for you.
ps: I just changed mine with over 130,000 KM on them on a 2.4L - they were NGK (were all that was avail at the time) and they came out fairly clean looking. Installed AC Delco ones this time.

I would re check the MAF sensor, they don't always get plugged back right.
If this is a VVT engine you may have disturbed one or more of the solenoid wires. It's a 2009, so chances are good it's VVT.

If one's not gapped correctly, it's best to return it for a swap out.

Not a ghost in the machine, codes will self clear after a number of fault free driving cycles.
Disconnecting the NEGATIVE battery cable as whopper suggested is what we refer to as a "Lobotomy".
If you have a CEL set and you have addressed and corrected to source of the fault, such as not reconnecting the MAF sensor, then you can clear the codes via the Lobotomy route.
But only do so to clear codes that you've addressed, disconnecting the battery just to shut off a CEL is not recommended, as continued driving with certain codes set will ultimately lead to damage requiring more expensive repairs.
