Hi all, so my 280Z with stock L28 with EFI has a strange fault where sometimes when driving the car it just starts to misfire and will not accelerate, but will idle fine. It just sounds like it's firing on half its cylinders (to a layman) when you push the throttle... however, if you turn off the car, leave it for 10 seconds, and turn it back on again, it's fine and will drive no issue.
When I drove to the Fourways meet on Saturday, it didn't happen once, until I arrived and it happened when I was parking up (embarrassing), but on the drive home, it happened maybe 4 times in an hour and a half.
I'm going to be replacing all of this soon anyway with more modern injection, but it means I cant reliably drive the car as I am too worried I will need to find somewhere safe to pull over to restart the car.
Any ideas on what could be causing this? I'm hoping its something simple I can fix myself
I assume its ECU or sensor related, like something goes out of range and resetting the ECU by turning off the car seems to reset it, but I have no idea
