Hi

I replaced both O2 sensors with original hyundai sensor(after cat and before cat) in Jan. 2012-I just cleaned carbon from engine with seafoam. The CEL is now on, my question is will cleaner(seafoam) throw my readings off that greatly as to set off the CEL? And will it go off when the readings stabilize?
