Another MIL Eliminator & reset codes Question

[soctty7676]

Ok, I tried the solder in MIL E's, cleaned my O2 sensors & reset my check engine light with a code reader. I thought everything was good until after about a week. Now, I am getting both 0430 and 0420 codes.

First question, does it reset the whole computer when I reset the Service Engine light with a code reader? Or does it just clear the codes. Every time I read the codes I just go ahead and reset the light for the heck of it. I am just wondering if the car has to re-learn everything every time I am doing this.

Second question, I am going to try the plug in MIL E's. Should I remove the soldered in MIL E's, or just leave as-is and plug in the new MIL E's. I am thinking I need to remove the soldered in one, but want to make sure.

I am going to be super pi**ed if the plug in ones don't work. Because if they don't, I am going to have to buy a tuner to totally disable them. Anyone know of any shops in the Naples/Ft. Myers area that can disable these for me?

Thanks!

well the code checker just clears the codes.....are you installing a new exhaust system and this is why you are using MIL-E's? If the answer is yes to this question then this is what I would do and have had to do myself....After the install of my bassini X and MIL-E's, I had to disconnect the battery, tap the break pedal a few times to bleed off any remaining voltage (leave it disconnected for a few minutes), connect it back up, and follow the procedure in your owners manual for "relearning" of the computer. I didn't do this when I put my cats back into the system for inspection and got a code for slow O2 circuit, did the above procedure, and no problems to report. think my code was P0153 or something along these lines, been awhile so I don't remember.

Yes, this is from installing a new exhaust w/o cats. The 0420 and 0430 codes are telling me the cats aren't working correctly. I tried solder in MIL Eliminators, the computer reset, cleared codes with a code scanner, let the car's ECU relearn itself. Still get check engine light. I'm guessing that it is outside the range that even the mil elim's can handle? Although I don't know why or how that would be different on my car than any other. This is why I am skeptical if the plug-in ones are even going to work.
