I got a service soon light in the upper right corner during a normal drive yesterday. The temperature was about 30F here in Chicago. It was during normal acceleration not full WOT. My two mods are Injen intake and Greddy Comp Ti-c TBE. The car is stock no tune. I had no issues for approx 9months no lights of any kind or problems.
I am on a second oil change due for third in about 500miles.

This is my reference : https://www.evolutionm.net/forums/ev...problem-x.html

Possible overboost because of cold weather and no tune? Any input would be appreciated.

P.S. I tried the fuel cap and restart didn't go away. Also I use Shell gas 93octane.

 

go somewhere that checks service engine lights and have it checked out to see what it is, or like it says in the first refrence you just posted you might be in need of a tune

 

(as above ) you need to get tuned bro

 

Go to Autozone or Pep Boys and pull the code. And get yourself a tune.

 

ehh i dont like autozone of pep boys, ADVANCED AUTO ALL THE WAY!! if were talking about walk in parts stores lol

 

First, thanks for your input. I still wonder why it took so long to have any issues with this setup if it was a problem would it have not happen sooner?? I will have the code read and then I will get a tune asap.

 

ehhh it could happen any time, as soon as one tiny thing goes wrong with your motor or your set up of parts in this case it will trigger a service light on any evo, its real common especially to get random misfire codes :/ good luck. its prolly just an issue with to much intake/exhaust flow

 

i had a sevice light when i was at like 2500 miles. went to the dealership and hasnt come on since.
