There are a few answers to this. Is you car throwing any codes. Jump the TE1 and E1 terminals in the diagnostics terminal under your dash left kick panel and see if your throwing codes. Could be MAF or O2. Thats a good start

To retrieve codes, turn ignition on. DO NOT start engine.
Using a jumper wire or paper clip, connect terminals E1 and TE1 together either on
DLC1 or DLC2(diagnostics ports). Count number of flashes from Malfunction
Indicator Light (MIL).
If MIL flashes 2 times every second, system is functioning
properly (no codes present). This is known as a normal condition. If a
diagnostic code is displayed, first group of flashes will indicate
first digit of a 2-digit diagnostic code. After a 1.5 second delay,
second group of flashes will indicate second digit of diagnostic code. (Example would 2 flashes pause then 4 flashes would be 24 AIT sensor signal.)
If more than one code is stored, a 2.5 second delay will
occur between diagnostic codes. After all diagnostic codes have been
displayed, a 4.5 second delay will occur and then codes will be
repeated until jumper wire connecting terminals E1 and TE1 is
disconnected. Diagnostic codes will display from smallest to largest
number.
Identify and record diagnostic trouble codes. After
trouble codes are retrieved, remove jumper wire to exit Normal Mode.

If its just non stop blinking 2 times every second then there in no error. You should have some sort of pattern if there was a problem being picked up by the computer. I would clean you TB, IACV, and MAF.

what kind of blinking is your car shooting? If its blinking about 5 times every second, you need a tune up badly. Could be a misfire and i believe its an emergency could for "take me to the shop now" Happened to me wen i bought my sc and after a tune up it shot me a code.
