I was at a track day event yesterday and half way through my service engine soon light comes on. The car felt fine and the oil was perfect. Everyone at the track told me dont worry about it. Anyone know what I should do? take my modified evo to Mitsubishi to see what the deal is? or take it to Turbotrix to check it? or does it just mean it needs a service.......

 

Take it to Autozone or a place like that, they can use their OBDII tool for you for free, tell you what the code is, then come back and tell us what the code/s is/are

 

i went to autozone when mine came on and all it was is my 02 sensor but there was nothing wrong with it just the tbe exhaust throws it off i guess.....but car is perfect....

if you cant feel or see anything wrong your proly a ok

 

I remember reading somewhere that when that light is on, the ecu is set to a safe or "limp" mode. You may want to get it fixed...

 

Have you had the P300 dealer reflash done yet?

 

Also if you hit fuel cut 3 times it kicks on.

^^^^^

when this light comes on from your install of a new exhaust , be aware that this has no effect on the performance of your car. its just a stupid reminder that the o2 (oxygen) sensor is finding a problem caused when you removed or did something to the stock catalytic converter.

 

I have the perrin cat delete with the o2 sensor... ive had it for 6 months and no SES light... any other thoughts?

 

Mine just came on this week too for the first time. I need to go get it checked but my car is running fine so I am not worried.

 

you're lucky? LOL!!! i have the same thing and my ses came on after a few days, as soon as i refilled the tank at the gas station. not worried about it here, i was going to put a piece of tape over it, but now it doesn't bother me anymore.

be lucky ours aren't bad. my bf's sti had a cel from his wastegate being too small and his cruise control light would flash while the cel was on. it was REALLY annoying..
