I recently got a header for my 2002 civic 2ith the non vtec 1.7 liter because my exaust manifold had a huge crack in it, the new exaust dosnt have a cat on it, my car has been in limp mode giving a code for the maf sensor, when i checked it one of the wires had came out of the plug for the maf, i replaced the plug but now the new header that rosnt have a cat only has the threads for the o2 sensor before the cat, will unplugging the secondary o2 sensor plug put my car in limp mode? Do i have to reset my ecu to get it out oflimp mode? Im not a mechanic but have very limited funds to spend fixing it, any advice would be apriciated

Also dose the o2 sensor eliminators actually work? And i was told you could reprogram the ecu not to read the o2 sensor s, is this true?

It Wasn't Me

Is this a serious question?

Yes.

Yes. Install one for the secondary o2 sensor.

The stock ECU cannot be "reprogrammed."
