Ok, first and formost, im getting a P0420. (cat low efficiency. .. )
im running a catted invidia V3 downpipe, and have been for almost 2 years now. never a problem with it.
my car currently has 60,000 miles on it. for the past 2000mi or so, i get that CEL. and keep deleting it. sometimes it comes back in 10 mi, sometimes in 300mi. . . .
currently i am running stock tune, with intake, inlet, uppipe, EL headers, the above mentioned downpipe, and catback.
i dont believe the cat is broken up or clogged so i dont really think the cat is the issue. but if it were an 02 sensor going screwy, wouldnt i get an 02 sensor code? ive asked around and gotten a bunch of shrugged shoulders...
any ideas?
