1998 SL 500 problems
My SL 500 has developed a "check engine light" problem which was diagnosed as " secondary air injection passages are plugged with carbon"
Does anyone know what to do about it?

the passages are inside the heads and they have to come off to be cleaned properly,it is a 15-20 hour job i think plus parts ,have a second opinion on it though,before you just do it,,,,good luck
