In any case if you had an active misfire you would see a constant flashing CEL, and a constantly illuminated CEL means there is a code stored. A lot of the OBD1 codes are electronics issues codes that throw when something is unplugged or fails in a specific manner, save for the air-fuel rich or lean codes. So there's a good chance the car will run like trash but you'll never see a CEL so long as the ECU determines that all the electronics are plugged in and believes they are functioning properly. if the CEL isn't illuminated, for the time being either the ECU seems to think all of it's signals are OK OR it just hasn't had enough time to figure it out yet.

You mentioned moisture and water built up in the spark plug, do you mean in the spark plug well or the tip of the plug? If the tip of the plug is wet this means there is fuel being injected into the cylinder but the plug isn't firing. Which plugs have shown this condition? Also note that this in particular is not usually a problem with the spark plug itself but instead either the coil pack or ignitor that fires that specific plug.

If there is moisture pooled at the bottom of the spark plug wells this also needs to be corrected as it too can prevent the plug from firing. Was there any corrosion on the spark plugs?

Lastly, signs of rodents are pretty obvious. You'll see feces, acorn husks, fur and tiny paw prints. If you've got none of those there's a low likelihood of rodents getting in your engine and even lower likelihood they went to town on your wiring. They prefer the insides of cars more frequently anyway.

did you try what i suggested? There was no need to pull sparkplugs

Yes they are the same....... Unplug on and start the car. If it starts the coil still plugged in is good. Cut car of do the same for the other coil

Glad it worked out... did you check the bearings on the IACV when you removed it and did you put on a new gasket? as for the squeak if the belts not old check the tension and also remove the belt and spin each pulley listen for roughness
