Default p0300 still cant get it right.

Alright. The 02 sensors were wired backwards. I got a diagram and fixed them. Now the values don't change. Would this have fried the ecm and or comp? Idle or wto the reading stays right in the middle of the range. It's Way to rich at idle. Thanks for any info.
