A couple of things to check, first try using the How-To link to make the adjustments if that doesn't work here is what to do/check. One last thing, if your clutch is also hard to disengage and finding neutral is all but impossible follow along.
1. Pull the belt cover off (3 hex screws)
2. Remove the the clutch adjusting locking nut with an 11/16" wrench
3. Remove the clutch push rod and inspect (should be nice and straight and come out easy.
4. Assuming your clutch is ok and keep in mind it can be shot with as little as 6,000 miles (just replaced one today). lets check the next thing
5. With your clutch cable still attached to the pulley cover check that when you squeeze the clutch the actuator turns properly. If not, take it apart and check for broken parts or a missing cable clip. If all is ok, re-grease and put everything back together.
6. Now its time to pull the primary cover to check the clutch and clutch pressure plate (this is was separates the clutch discs when the rod pushes against it).
7. Squeeze the clutch and verify how far it moves out (separating the discs) when squeezed.
8. If the pressure plate moves out to spec then your clutch pak needs to be replaced so be prepared to spend $200 for a new pak.
I took a bunch of photos during the disassembly and re-assembly process I will add to a how-to -- there are good ones there now!.
