Don't know of a shop that can do this, yet? I pulled the plugs earlier in the week. They had the tan/grayish color of normal running plugs. They did appear very "wet" on the bottom threads. It's been started numerous times since then, who knows. A new set, once I determine the injector problems, will be in order.


Wonder if spraying the throttle body, I've dislodged some gunk? The rough running started after I did that. Looks like I have more work ahead of me.

Good chance you did, most likely coated the plugs with that crap you sprayed in the throttle body. Screw a set of plugs in it, and your dead cylinders will probably go away.
