I’ve been having a slight misfire/pop on deceleration occasionally since I bought the truck. Doesn’t happen all the time, but often enough. I presumed there to be a plug or wire on the way out, so I picked up cap/rotor/wires/plugs and did the first tune up today.
Immediately after pulling the air intake/Vortec box off I saw a gift from the previous owner. Dizzy cap had one broken screw, that couldn’t be helping. Moisture/corrosion on the aluminum contacts inside the cap too. Was able to remove broken screw with relative ease. Rest of the tune up went smooth, and did a lengthy test drive after and didn’t notice anymore misfire issues. Truck feels like it’s “woke up” a bit.
Found some cracked plastic wire loom in engine bay as well, so taped that up after verifying wire integrity as Ok.
All in all, good day under the hood. Some Pics attached (had more but there a limit of 5), plugs were gapped to .060. They all came out of the box at about .055
