Over the last winter I have put the comp tech headers and exhaust with new O2 sensors on my 91 nsx. I also replaced the stock air filter with the uni filter and cantrell scoop as well as short gears and clucth. The problem is my engine light keeps coming on... fluids are right, performance is good, the light seems to reset when I turn off the car but returns 5-10 min into the next start up. I am concerned that I may have missed something? Any suggestions ...Thomas

You need to get the code, do you know how to do that?

You'll get a better idea of what's going on by pulling the code on the check engine light.

Carefully check the pins in all eight O2 sensor connectors, especially the extensions. Make sure all are at the same height / depth, and none have backed out.
