If there was a lot of Prestone in the fuel line, then the filter sock on the pump could be clogged which is in the tank.
Question: If Antifreeze was present in the fuel, wouldn't that cause steam to come out the muffler?

We used to have a Plymouth Voyager, which I now suspect was killed the same way by our landlord.
When the head gasket went, it did that. On the Ford, this time, that night and right afterwards, the interior of the windows fogged up the same way, with a goo I could not clean off, was sticky and smelly. It smelled just as the head gasket problem had, but we never had white smoke, leading me to believe the landlord anti-freezed the gas tank. Antifreeze does not clear out of the engine as sugar does.
I did attempt the rear spark plugs, and was unaware of the air intakes, and here was no mention of how to do it, either. I figured out one just pops out, and it will be a snap tomorrow. After re-hooking up the battery, the car runs better, and the CEL lights stopped, it just needed to be reset.
It is still stalling when it slows down. Someone on this forum stated it coudl be fixed two ways, which one is best?:
1. Isolator bolt fix, as done here...

or,
2. IAC valve clean.
I have down the valve cover in the past, but suspect that is not the problem here, but rather the sound being made is the fuel injectors and spark lugs-it was cut in half, soundwise by replacing the front 3. Since the isolator and fuel rail are in the same process, figure I would do the plugs first.
