hey mate.It had a miss fire at 10 psi.Put new plugs in it.Gapped them to 0.8mm.Found minor vacum leak fixed that.Took it for a drive.Miss fire seemed to go away a little bit.Only happens under boost(heavy load).Played around with boost a little bit now miss fires bad from 8-10 psi.What do ya think this would be.Coils maybe?They were lookin the best.
