Well it doesent have an ignition problem or mechanical shortcoming at all judging by the hc.(but it soon will as i said before bosch standard platinums arent worth a dime , see plug thread)And the co doesent seem excessive if this is loaded on a dyno .I would say the converter is shot. one more question do you have the o2 measurement by chance? If the oxygen content is excessive it also indicates poor converter performance ( it has to use up most of the oxygen in the process of burning off the pollutants) Just went back and read all the thread and Id say with 130000 and what youve already done combined with the gas readings replace the converter and lose the bosch plugs and youll be good to go. And please by all means post your results I have a good reputation to uphold .........
