:confused:
I have a 94 Civic EX Coupe. I also have a JDM Chip installed. I recently have been getting a check engine when ever I'm driving under normal conditions but when I street race the check engine turns off. I only use my car about ever 15 days or so. I have changed the water pump around two years ago as well as the chip.

What could it be? If I turn the engine off the light turns off and when I start driving under street legal conditions the damn thing comes on again.

Is my ECU going bad or could it be engine problems?

i got a JDM b16a with the JDM computer and the light is always on... i dont think its a problem cos everything is neat and serviced...i wouldnt worry about it at all unless you are certain something is wrong with your car
