cel question?

[Zultane]

So I finally just picked up my eclipse yesterday It was 9 hour drive. Bought it from a friend from my hometown. I'm literally driving right now, I'm on i70. But im noticing something weird.

My check engine light is on, if I'm at cruising speed. About 80mph. AFR reads 15.3 give or take. Now, if I open up WOT, after I start boosting, the Cel turns off. Under boost I'm at about 11.1 AFR. when I get back to cruising, cel comes back on. Any ideas?

I should also note, at cruising speed, I'm at about 0psi, when I'm on it, it's around 12 (which I'm pretty sure is low) it also idles pretty bad, and apparently lurches forward, even if the clutch is pressed.

Could be a bad sensor get a code read and let us know what you find then you can see what the cel is telling you.

That'll be difficult while driving... and it doesn't come on when I'm sitting still. Only when I'm driving

I have an apexi "super airflow converter" sitting next to me. That I know worked last time I saw this car, and now it doesn't have the display. Would that maybe have something to to with it?

Your going to have to get the code read thats the only way youll know what it means, check it when you get home.
