Hello! I have recently purchased a 05 anniversary edition Z. I have been fighting misfires and small stuttering since I bought it. My car is a DE rev up to DE non rev up swap and it uses the original rev up harness and a NATS disabled g35 ecu that is from the same g35 my motor is from. The car has lots of popping at idle but once warmed up runs relatively smooth besides it begins breaking up between 2000 and 3000 rpm and tends to have a combination of popping and rpm bouncing at idle. I have replaced so many sensors injectors and even the fuel pump. I have still not ran a compression test but the car runs good at speed.I have attached a video of me holding the rpm between 2 and 3k and you can hear it breaking up/ popping,I have also attached a video of the idle. So I am looking for some extra info/help.
