I have an 03 Fairlady Z, recently had a hot start issue, would start then stall, so I decided to clean the TB, since I've cleaned the TB I've had an issue where if I start it after having it sit for a night, it'll miss and sputter for about 10 seconds and then be fine. The hot start issue is also gone.
I can shut it off while it's acting up, start it up again and it'll start fine.
When it starts to act up it fluctuates between 800-1800 rpm and sounds like it's going to die, has one else had this issue?
No CEL or codes.
