Hi Guys
i am new here and would apreciate some help.
i recently purchased a 97 deville with 151 000 miles and the previous owner removed the catalytic converter.
i know its illegal but i got no $$$ to buy one right now and have it installed.
Luckily i live in MI and they do not test emissions.

he was stupid enough to cut off the o2 sensor and leave the wires dangling. !
i found in another forum people hooking a Diode to fool the PCM.
i tried it with no luck. i keep getting the P0146 code.

Has anyone had that problem before?
Any tips would be greatly apreciated.

Anybody messing with this is subject to a substantial Federal fine.

Easy fix. 97 Deville?? Replace the O2 sensor and the cat + pipe with the sensor boss. Meets emissions and code gone.

Initially, it was illegal, under Federal and probably State law to sell an altered vehicle. The seller broke the law and so did you. Regardless of whether the individual state or jurisdiction tests for emissions or not, the vehicle must be equipped as delivered and pass federal standards. No ifs, ands, or buts.
