o2 sensors???

[BLck89accord]

i finally got my dc sports header on today and i love it....one problem tho....when i got out on the road tonightm ny check engine light came on but the car was running fine, so i parked and started car again......after a few miles, light came on again. Weird. I'm wonderinf if its becasue of the O2 sensors, which still remain stock, on a brand new header???? I picked up 2 new bosch O2 sensors for my car tonight in case that is the prob.? Check engine light has never come on before til now for me.

they may go bad from the manipulation.

Check if the sensors are plugged in the proper way. The DC header design inverts the O2 sensors.
