Anyone clean the 993 secondary air ports?
Wondered if anyone out there has tackled the PIA project of cleaning the clogged SAI ports. No need to pull the engine and heads if 'ya don't burn oil at an undue rate.
I've heard of folks that have pulled the intake and exhaust, poured carbon cleaner down the SAI ports and cleaned out with pipecleaners or wires.
Anybody actually done this that might offer tips and/or shortcuts?
