    Check engine light at WOT

    Before anyone says anything, NO I have not read the codes, I really need to do this however I'd like to get a jump start on what this could be

    Car = 1991 Mitsubishi Diamante 30RS (JDM) 3L DOHC automatic.
    *sometimes* if I nail it, funnily enough, usually at night, I will get a check engine light appear on the digital LCD readout.

    What could be the cause of this issue? The check engine light will go off once i turn the car off and restart it. But will only happen when my foot is jammed to the floor *sometimes*

    Where could I start looking? And yes, in due time, Will be doing a code read
    Also, car feels fine when the check engine light is on. No loss of power or anything, feels totally normal.

    Fantastic. Thanks buddy. I only have ~20 of these spare so that's good if its possibly faulty. Might explain why sometimes at WOT the prick doesnt downchange.

    Thanks!
