But do you think it will pass? Ya, 97 degs. of overlap should play hell under 2000r`s.............I`m mostly looking foreward to their faces when I put it in the bay and rattle the place apart. I`ll also compare a modern day 5-gas analizer to my "gross polluter"......could learn something plus I`ll note my wide band #`s at the tested rpm`s............fun stuff.....oh ya, I`ll be leaving this class w/an A and at least one cert. I`v learned more in two months(crash course)than I have in two years in terms of ALL of the sensors and their role in these modern marvels and how to test em to verify their condition(s).
