1/2 ton status
'88 Suburban with a 454 and 120,000 miles. Recently purchased and has a slight miss that is worse when cold. I changed plugs and wires, changed oil and some other minor stuff that I normally do when I purchase a used vehicle. Here is a pic of the plugs. Anything out of the ordinary going on that you can tell. I'm not real knowledgeable on motors. I know enough to do regular maintenance and change parts
It still has a slight miss after replacing plugs and wires.
I did find a couple of the plugs loose when removing. I can't remember which ones. I pretty sure #4 was loose.
