Glad you found the issue. Sorry it was such a headache

It's all good, no one could have expected the "so called mechanic" to have ground the engine improperly and cost me tons of fuel economy and repairs to various electrical components.

If you are in NY and meet a Leslie Frizzell, don't let him touch your vehicle. That's all I can say!

Certainly was Gremlins, although caused by a human feeding them after midnight and getting water on them.
