misfires and wet plugs LS6 heads/intake, TR220, push rods, LT - new parts. All else stock 99.
Many misfires at idle on 5 and 7.
Plugs 5, 7, 8, are wet with gasoline; I have spark on driver side and swapped plugs/wires on same side. No real change. Verified good spark on driver’s side. Will test passenger side.
1 and 2 are soot covered.
The plugs are either gas coated or sooty.
Did lots of searching and found you can delete the misfire, but that does not seem like a solution because their is not firing on the rear cylinders [ie the headers stay cool].
Next on the list is compression testing.
What is the potential resolution? Thanks.
