Default Check engine light back on because exhaust leak

So yea...I had an exhaust leak and that made the check engine light turn on again even tho I have the MIL Eliminators for my Prochamber...

so how do i get it to turn back off....should I just unplug my battery for like 10minutes so the computer resets?

Thanks

Could be one of you MIL's is getting a slow read. Same thing happened to me when I installed my LT's w/ MIL's. I took mine back and swapped them out. Problem solved

do you know what code your getting? P0420 and p0430 would be caused by cats or mil eliminators not on. yes you can disconnect battery for 10 min and light will clear.. don't know of any codes caused by an exhaust leak... except maybe lean..

Get a tuner and turn them off for good and then youwon`t have to worry about the CEL.

the mils were working fine (ive barely had my OR Prochamber and mils for like a month)...

then the pipe got loose from the headers and i had an exhaust leak...
the check engine light came on...

i had the bolts put back on, but the check engine light is still on...i will try to disconnect battery for10 mins and see if that works....

if the light comes back on... then you still have an issue. Might be something altogether different then exhaust. If you can tell me the code i could probably walk you thru it.
