okayy im still new with all the honda stuff so i dont know much. barley got my car a coiuple months ago..thats why i asked this question so i could learn.
my check engine light turns on
before it only turned on when i take my car pass 55
but todayy when i was on the way home from school it turned on at 40
and kept turning on at 40 since then.
so any reason why this is happen?
i have a 1988 ef. stock motor.

 

well i'd start by checking to see what code is popping up. turn the car to run but don't start it. pull back your passenger side footwell carpeting and count the led blinks on the ecu. do a search for obd0 ecu codes and then use it to figure out what your car is pissed about.
