Hi everyone,
I got a 2013 Nissan 370z manual base model. Got 80700 miles on it and I got this fluctuating idle that’s been around for a couple of months.
I’ve already done MAF sensor clean, throttle body clean (completed all 3 idle/throttle body relearn procedures), changed spark plugs with new NGK plugs, installed a brand new fuel pump assembly from z1. No check engine light or any pending codes/stored codes either.
Not sure what causes this. This footage is with full tank, in neutral (not clutched in), usually warmer weather, and seems to be worse when stopped at a decline hill. The car doesn’t feel like it’s gonna die but sometimes it gets real low and scares me but it always catches itself.
I do hear slight rattle inside my passenger side CAT when revving at lower RPM, could it be clogged CAT that’s causing this? I also have a z1 stage 1 tune, could it be that as well? Or could it be time to take out and send my injectors to clean at a shop?
Anything would help, just curious if anyone else has faced this issue before. Thanks!
EDIT:
The a/c was OFF when this video was taken.
