Engine management light flash

[ScoobyJoe]

Hi all! 

Brought my first Scooby about three weeks back, and I fell in love with it straight away! It's a bugeye WRX wagon.The car is completely standard bar a prodrive Backbox & an STi intercooler. Cambelt, tensioner & pulley was done 2k ago.

Yesterday I accelerated hard in 4th, and when I got to about 80, the engine management light flashed on/off for about 10 seconds.. It's not come on since & the car drives fine. I'm completely bamboozled! The boost reading was normal, any ideas? 

Any help would be much appreciated, as I'm not able to get it in to a garage till next week.

Best bet would be have the code read to see what popped up.

Will do as soon as I get the chance mate, any idea what it could be? From past experience maybe? Like I said I've not been a Scooby owner long, so I'm just really confused why it flashed for a bit then went off.

flashing ECL can be misfire detected, worth checking plugs & leads if no useful codes or other faults found .

Make sure plug gaps sensible & decent brand & right model while you have them out as when on boost the higher compression & more fuel creates greater resistance for the spark ...

O2 & knock sensors can intermittently flash and dissappear, they'll be stored in the ecu though

Cheers for the response guys, my immediate thought was the 02 sensor or dodgy spark plug! Will be getting it in the garage asap.

Worth buying a cheap code reader or cheap cable, obd adaptor to use with pc or android software so can read your own codes .

Literally just ordered one on eBay mate!
