Default 95.5 4.0 Engine Won't Accelerate

I discovered a new problem today.

The engine starts and idles perfectly but won't develop more than 1000 RPM and has minimal power.

What happened? Oh yeah well I decided to rinse out the AC Condenser with a hose and then this all started. Well, I was a mile down the road when it started.

Q: What is this mysterious problem?

A: Water in the wiring harness for the crank position sensor.

Resolution: Took the connector apart (front of the engine above the alternator), blew out the water, sprayed in the WD-40 (Water Displacer - 40) and all was well again.
