Don't know which part of "you cannot set the timing if you have ANY codes present" I was unclear on but you cannot set the timing if you have ANY codes present. So, if you had codes present you didn't actually set the timing... more likely put it off by 40 degrees.

The TPS is a wear component. If it's not reading within the range specified in the TSRM then you need to ... (care to guess what I'm about to say?) ... replace it.

Um, is this a rhetorical question? Electricity + wiring + spark plugs + water = bad stuff (in this case a short), so I'm going to have to say that there's a strong possibility they're related.

Pull the plug wires out and check how much coolant the plugs are swimming in. If it's a few table spoons then just pull the plugs and let it drop into the cylinders (there's no way you're getting it out... not even with a straw and it'll burn off in just a few seconds). If there's more than that the start pushing paper towels in there and soak up as much as possible. Dry the plugs and the plug wires very thoroughly.
