Haven't been able to get into a diagnostics machine yet. But yeah i think that sounds logical to work my way back to ecu from cas. With the injectors seals, I've even swapped fuel rails with injectors in it. And it made no difference. In the back of my mind I still think it's just throwing me some red herrings. So many different things I've been fiddling with when it all just started with a bad ground. It's never ending!
did you ever find the issue? i am having literally the exact same problem with my sr 180, nistune 480cc injectors and z32, it is driving me crazy
I did manage to resolve this issue for me in the end. Went standalone ecu with brand new loom and plugs. Not cheap mind you. When I pulled the old loom out I found 2 broken wires. 1 was orange, start signal I think, another was purple, can't remember what it done. But defo something that effected idle. So I'd defo recommend checking out the loom. They are all old and crusty now they 30 years old!
