Those pics don't indicate flooding to me. I would bet there are lot's of people who have fuses like that but don't know it. Replace em and you're good to go.

I've had battery poles looking like that when I lived near the sea. Back then my tree shade mechanic showed me how a cup of coca cola (or whatever soft drink) would clean up the battery clamp to a shine. Neat trick if you're ever stranded with a no start and suspect a corroded battery clamp.

Just a bit of an update. Wanted to let you all know how the restoration was going.

I finally got her going. I posted another post about it. Basically, one of the injectors was unplugged and it needed a new crank position sensor.

She runs pretty well down the highway and I'm just left guessing about a hesitation between 1000 and 2000 RPMs. I changed the plugs over the weekend and they were pretty much toast. One of them had a pretty corroded cap on it. At first it seemed like that solved the problem, but it's still there. Seems less.

I'm going to sort through the rest over the weekend.

How are the other tune-up parts like plug wires, caps, rotors, etc? Those are the OEM 3-prong plugs. Considering the condition of the car and its age, if those plugs were in it, I'd have to wonder when they, or anything else, was last changed.

Yep, general tune-up needed. Break down and spend some money on the car!

Don't forget all the deferred stuff, like flexplate check.

You talkin' about #1? If you're not going to spring for a set of the Beru plugs with new boots, then get a pen light and check the business end of the #1 plug wire boot for matching corrosion or damage. I had a car with an intermittent miss. The contact point with the plug deep in the boot was damaged and corroded and not always making good contact with the plug's head. The plug looked like your #1.

I have a set of wires on order. They look pretty good and I haven't noticed any sparks when the garage is dark. There is a hesitation at low RPMs, so there could be something I can't see.

+1 on the plug wires.

Funny thing is that I had a set of wires left over from when I changed them on the other one. I checked out the plugs that had corroded tips and changed out the boots.

This may have solved the issue. A short trip around the block seemed to run smoother. Need to take her on a long run to make sure. And even though the issue is at low RPMs and speeds under 30, I better make sure I test the 80+ range as well. And make sure that the replacement boots can handle plenty of twists and turns.
