Cadillac El Dorado Engine Problem
I was told I need to replace the Engine control module so I went and bought one. I need to know if there is any special procedures when replacing it or any info you can tell me on reseting the codes but keeping the same programing. Thank you!

You won't have to reset any codes because you are removing the entire ECM that holds the codes. You will have to swap over the PROM from your old ECM.
