There is no compression in @1 cylinder all the rest of them have around 170 pounds. I don't see no mix of fluid's from head gasket how would I know for sure where the compression loss is going?

Squit a small amount of oil into the cylinder and retest, if reading improves, its rings, if not it's valves, you may have a stuck or burned valve, which is more likley than not!

If you have oil in the antifreeze, it's time to remove the head and send it to the machine shop to be checked and valves grinded.

If you follow the wires, you should come to the connectors, on one of the flat sides, push down on the tab and pull apart. One the the throttle position sensor, and the other is the idle air control motor/valve.
