we swapped back to the old coils and same thing. we swapped coils around to other cylinders, swapped spark plugs didnt swap injectors as this side of things is new to me.
i degreased and washed the engine bay a few days before, sorry forgot to mention that major part of my situation.., my reckoning is that waters gotten somewhere in the injector loom, cos the sparks look pretty consistant (its hard to tell cos idle is sloppy) ,, this is so frustrating!!. how can i check dirt in the injectors? thank you so much for replies im new to the rb engines they go so hard.
