CEL after installing MILs?

[302fordracer]

A couple weeks ago I put on my bassani o/r x pipe, it took a week or so to have the CEL come on and then I put on the MILs. Now last night, the CEL came back on. The car runs perfect, no issues at all to complain of except the light coming back on. I ordered a programmer in the mail, so soon enough I should know for sure what it is, I was just wondering if anyone has had the rear O2 sensor code trip after installing MILs?

Would help to know what the DTC code really is. What if it is not related to the rear O2 sensors?

I don't have my programmer yet, it is in the mail...when I get it I'll read the code..until then, I was just wondering if this had happened to anyone and it it could be the rear O2...I certainly hope it isn't anything else, but as I said, no driveability symptoms whatsoever..

got the code read...PO430..bank 2 catalyst insufficient.

Sounds like your driver's side MIL is malfunctioning.

when I was running mil eliminaters, I'd get cat efficiency codes, everytime I cleared the codes or reconnected the battery, after sitting for the winter. If I kept driving it, the light would go out after a few days of driving and would not come back on again.

oh cool, I was just wondering if anyone else has had this happen..doesn't really matter anyway though, gonna program it to ignore the rear 02 now anyway..but thanks everyone!
