Service engine soon light blinking
Hey guys, I'm a newbie from IN, just got a Evo 9 with 25k miles from TX. Got a problem of my car, not sure if this is the right place to ask, if not, plz tell me.
Last night I was trying to wot at 2 gear, at 2nd gear about 4000 rpm, engine service soon light started blinking. When I shifted to 3 gear then, everything is fine.
when I was driving at 4th gear then wot, when it was about 4000 rpm, light started to blink again. Then shifted to 5th everything was fine.
Afr was about 11.5 and boost was around 24 at wot, using 93 shell.
Can anyone help me since this is my first manual car and Evo is my dream car, really want to take good care of it. Thanks!

Blinking CEL light is usually an indication of knock, if you have tephra mods in your ecu. Read up here: http://evoecu.logic.net/wiki/TephraMod
Basically no blink = zero knock count, slow blink = low knock count, fast blink = high knock count.
If you have a tactrix/evoscan cable and software, log a pull and check your knock count.

Also, doing all the basic maintenance is always a good idea if you don't know the previous owner very well. I'm not saying to distrust the last owner but it does give you some peace of mind knowing that everything is up to scratch.
As above, plugs, boost leak and retune and you'll be right.
