Please Help - Car Failed Test

[angman]

Hi guys I am in need of help. My 97 box failed its emissions test and I have 2 days to fix it and pass the test before the box goes into winter storage again.

My problem is that in the Hydrocarbons test the maximum allowable is .5000 and my car read .7721

The carbon monoxide and NOx test passed just fine.

I started getting a CEL when I installed the cheap aftermarket headers. The car was also in storage for about 8 months before I started it, did an oil change, ran it for about 1 hour before the test (with the stale gas). My questions is should I swap back to the stock headers and hope all goes away? My headers had 02 bungs for later model cars but my model year only has 2 sets of sensors. The 02 bungs that aren't used on the new header are plugged up with old 02 sensors to fill up the holes.

I have a OBD2 reader attached and it reads:

P1125
Oxygen sensor adaptation, upper load range, Bank 1, above limit.

Anyone knows what this means?

Perhaps I just need new 02 sensors? Or maybe the new headers aren't working with the onboard computer? Perhaps the 02 bungs on the new header is leaking air? Perhaps the new header wasn't installed well and is leaking air?

I am no emissions expert and not even sure why the header would affect the results. Perhaps it was due to the car being in long term storage? But the CEL was on.

Thanks in advance
