What is the CO reading suppose to be (range?)
and at what RMP are you testing this?
: Hi everyone.
: I have an '89 Euro M3, with the catalytic recently removed, showing a CO emissions reading of 0.68%
: Is this too lean? It has an uneven idle which suggests a lean mixture caused by the dreaded inlet manifold gaskets but these have been checked and are not leaking. Any suggestions?
