Misfire on cyl 8.
Both banks running rich.
Both catalytic convertors blown open
Probably an injector stuck open.
Will cause hydro lock and could bend a rod.

 

It is most likely cylinder 8 misfire right

I read it and what are the chances it would be that it only miss at idle but not all ways

 

Two bolts hold the fuel rail down on each side. Take the two bolts that hold the fuel rail On the driver side and lift the fuel rail up with the injectors still in the rail. You should be ableto see the bottom of all four injectors now. Turn the key on and see if any starts leaking fuel out. If it does replace the injector.

 

Number 8 is the rear on the driver side.

 

ok well i pulled the plug out and not that bad and swaped coils and still the same codes but i all so did the ohms test on the injectors while it was warm and it was still good and what size is the bolt that holds the coil down it is missing 4 of them i need the tread size

 

And I will try the thing with pulling the fuel real
