Not likely. Unless you've created a leak AFTER the MAF sensor, the cai isn't causing a false reading. You might also be hearing the evap purge solenoid doing its thing.Could the engines computer be misreading the air flow from the cold air intake? Maybe the it needs a tune for the air intake?
That's what the noise was on my car. Here are a couple of threads about it.Could be the evap purge valve...search it here for info...several threads on it recently. Just under the HPFP.
