This could be due to random transient ECM failure. Apparently the incident and recovery occurs too quickly for a code to be stored.

The check engine lamp will flash when the computer/emission system sees a problem that could possibly damage the catalytic converter or other components. Often the cause is a cylinder or cylinders that are misfiring which will make the engine run rough. Because the light has been flashing you should have the problem checked out and repaired to avoid any possible damage. Good luck, hope this helps!

Most likely culprit is the ETC (electronic throttle control). Different companies call it TPS (throttle position sensor) i.e. but what's happening is when the car is cold, the initial throttle setting is high until it warms up and kicks down to a secondary throttle position. Since these things are monitored electronically, there's nothing you can manually set. The part itself ( i think its TPS in your car) is usually a black component with an outer white layer located under the air filter. Hope this answers your question. Best of luck.

Have you checked the automatic shut down relay ?
It powers the injectors from a 20amp fuse number 5.

When the service engine soon light a yellow light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
