Exactly.. Let me give you a little story..
I put the O2 cheater in place and like a couple weeks later the check engine light came on. So I was like damn, I spent $35 and the light still comes on. Well during the warm up of the car it would hesitate and shake back and fourth until it was fully warmed up. I didn't think it was normal, but it seemed allright because it only did it for a little streatch of the road. I eventually went to the ford dealership to get my headlight fixed and I told them what it was doing. I also told them that the check engine light was from the O2 sensor. But I said they should check it out anyway. So they did, they called me back and said it was just the 02 sensor. She said she couldn't fix it because I modified the exhaust. I was like, ok, I told you that that light would come on. That still didn't solve my spuddering. So we got in an arguement and I went down there and talked to the manager and he had me talk to the tech. It ended up being the FIRST 02 sensor. I had extended it to make it reach the bung in the header. There was no light for the 2nd one with the o2 cheater in place. He said that I couldn't actually extend the sensor wire, I would have to extend the actualy harness that it hooks into. The wire is very sensative.
So thats my story, and after I read it I don't see how it fits in, but the O2 cheater is worth it because it showed that I had other problems with the car.

Ill have to disagree with you. Let me tell you why...
I have the same problem you descibe with the warm up issue and I DID NOT lengthen the 1st O2 sensor wire. This was after installing the FC header and a Steeda fuel rail.
Making the wire longer or shorter will NOT give any mis-readings. The electricity running through the wire doesnt care. (you would have to lengthen it a long ways for the resistance to change enough to matter). Now , possibly if you didnt splice/solder the connection well, that might be a different story.
