Re: 1JZ - Missing under boost - Farts like gearshift...

My EVO did the same thing a while back.
It was one of the plug leads, the part that goes into the head had a tiny split in it and it was arcing to the head.
New leads fixed it.
I know the 1JZ doesn't have plug leads as such, but it could be a similar problem with the part from the coil to the plug.
Or one of the coils could be knackered!!
