MIL Light Eliminator
FYI - I installed a home made MIL light eliminator (instructions found on WEB) but after 4 restarts and drives the CEL came back on. Guess I either live with the light being on or look for a pricey converter replacement.

MIL's only work if you have an operational O2 sensor. If you have a bad sensor they will not work.
I agree with the poster above, what is your current code, what was your past code? Might be that you just need to replace the sensor.

Original code was 0420, worn out cat. Pulled O2 sensor and ran the bench check using a propane torch and the voltage seemed OK. Haven't checked to find out out what the new code is with the MIL eliminator installed. Need to make a trip to Autozone.

P0420 Catalyst System Efficiency Below Threshold (Bank 1)
Yeah, that code normally indicates a bad cat. Your MIL should work just fine if you have a good O2 sensor. Where did you get your MIL? What is the new code?
