PLEASE Help!! Engine Light PO 136 caused by my own stupidity

[Scirocco16v]

1996 240sx SE Manual 5spd 110,000 miles

Engine CODE PO136

Hi all,I made a mistake by cleaning my throttle body while the engine was one with some brake cleaner. The car immediately stalled and my check engine like came on, PO136. I reset the light a few times and it pops back on 20 miles later. The manual says to check for intake leaks, which I've done numerous times, visually, without success.Is there anything I should check for?

Should I change the cat and second 02 sensor? I need to smog the car at a test only center. The vehicle sniffs clean but won't pass with the engine light on. Is there a way to bypass the sensor to get rid of the light, perhaps?thanks in advance for any help!! [email protected]

just replace the rear 02 sensor

Thanks....but it's not the sensor. The second sensor monitors the gases that pass through from the first cat. It's telling me that the cat is pretty much gone. Many would think that it's as easy as changing the cat for $100. Unfortunately, in California, a law made two years ago, made it illegal to weld on non obdII CARB approved cat. In other words, I need to throw down $500 for a new cat.

I think the best thing for me is to figure a way to trick the ecu that the sensor is working correctly, perhaps with a Resistor? Can anyone out in NICO land help or have any tips on this? thanks.
