Its been consistently 20 degrees here and usually windy, so I havent even opened the hood yet. I am hoping maybe on this or an upcoming weekend the wind dies down and the sun shines to make the 20 degree weather a little more workable.

Everyone tells me the whining is likely an alternator pulley, I will check fluids first though. I previously was unable to find the power steering fluid on the last few checks. But I dont suspect it to be power steering since I hear whining when driving in a straight line. Trans leaks were all fixed, but I will be checking that to be extra sure.

I was reading that a good way to find vacuum leaks is to spray carb cleaner around hoses and listen if the engine revs up a bit.

So it occurs to me that I currently have every symptom of incorrectly gapped plugs. This week there are going to be 2 warm days so i plan on taking off work a few hours early to check this. I suppose its entirely possible that I am running rich because the previous owner didnt gap their plugs, at least from what I've been reading it sounds like it could be one of several contributing factors.

I am actually kinda hoping the gapping is all wrong because then I can fix that and see how things run.

Most times, the plugs are properly gapped right out of the box. If you are going to be removing the plugs, you might as well just replace them all, since new plugs aren't that expensive. There is a better chance that the plug wires are defective than the plugs themselves. Also, the "dwell" of the ignition points should be checked, and the timing properly set.

I had thought that too, but of these 8 ACDelco plugs i bought awhile back I checked them all today and some were all the way to 0.40. Got them all gapped though. Current wires are new, I do know that much

Changed all my plugs yesterday. A few of them were soaking wet with gas too.

A few of those boots were stuck to the plugs so I ended up breaking 2 of them. I'm picking up a new set of wires tomorrow morning. That passenger side farthest back plug though was a bear to get out. My ratchet was a little too bulky to get at it so it was quite a challenge.

Also was considering trying some seafoam

Doubtful that choke is closing better chance at winning Power Ball. The gas additive not a bad idea to get rid of any accumulated water. I think the reality is the carb just needs to be rebuilt properly when the budget allows. Glad to hear you are on the road its needs the cobwebs shook out.

I know its really hard to tell which one is the old spark plug right?

the tips of the plugs that the boot goes over, those metal tips were just falling off when I was pulling them off.
