'87 4kq: brief shifting problem

I have to agree with Josh on this.  He wrote:

Run this test above and see.  Some things that would cause the clutch to NOT
disengage (in no particular order):
1. Floor mat under the pedal
2. Clutch pedal out of adjustment (although this wouldn't be intermittent)
3. Low fluid in the brake fluid resevoir (should trigger a dashboard light)
4. Clogged hose from the brake fluid resevoir to the clutch master cylinder
5. Bad seal in the clutch master cylinder (check inside the firewall for
fluid, pull the boot off and feel with a finger for wetness)
6. Bad seal in the clutch slave cylinder
7. Broken diaphragm spring on the pressure plate
8. Warped pressure plate
9. Warped clutch disc
10. Warped flywheel
11. Seized pilot bearing (in the end of the crankshaft)

Let's hope it's not 7-11.  Those are a bit harder to fix...
