help me please!

Today I had to add a couple of feet worth of wire on my O2 sensor on my 2000 Civic EX, because I got a aftermarket header. Originally the O2 sensor was at the end of the header now I had to move it up to about the first bend of the header. Now, the damn "check engine" light itsalways on. My ideas are that I added too much wire or that the conections are not good enough. My questions are,

1. How long can I go until I get this fixed?

2. Will this cause any damage until I get this fixed?

3. Does anybody make a O2 sensor extension, that I can add after I buy a new sensor?

Thanks,

Jeremy

Disconnect the batt and then connect it and see if it resets it, thats my guess.

That did the trick, thank you. Now I have to find the radio code.
