Once warm my D1 wont rev past 3k, so I want to confirm that my cats are clogged and was thinking about pulling the o2 sensors. Obviously, this will cause codes, but it should confirm my cats are clogged.
two main questions.
a) is the o2 hole for the exhaust big enough for my test?
b) could this cause other damage.?
