OP, any mods? intake/exhaust, etc? This code is generally thrown with an aftermarket intake.

no intake and no exhaust. no mods that would directly have a connection. Only suspension

At that point I would definitely side on the issue of bad/dirty MAF sensor(s) or faulty O2 sensor in one of the cats. You should not be throwing this code in an unmodded car.

If those are fine, like others have said, I would check the coil packs and also for vacuum leaks.
