Clutch finally going?
Well, when I bought my 944 back in the summer of 2000, the PO/mechanic said that the clutch would need to be replaced "soon"...
...and now, 3 years later, all of a sudden the clutch pedal feels "spongy" - it takes less effort to push it in. THe accelleration doesn't feel quite as brisk as it used to , and when I put the car into gear, it doesn't quite grab like it used to. Does this mean that my clutch finally is nearing the end of its life?

Is the tach getting away from the speedometer? Relationship is linear.

i think so... it seems like the speed should be higher than it is with the revs in each gear

1st and second feel ok as long as I get on the throttle early. Third doesn't feel as spunky, and if I floor it in 4th there is hardly any accelleration at all. Is this the clutch? the reason I think so is because the pedal feels really soft and easy to push in.

When you floor it in a taller gear does the tach get away from the speedometer. If the tach rises 25%, the speedometer MUST rise 25%; otherwise your clutch is slipping.
The soft pedal could indicate clutch needs bleeding. Do the test Aaron suggested. If the clutch is worn out, you're going to have to replace it anyway.

would bleeding the clutch be a temporary fix until i can afford a Sachs spring center dealie? is it an easy job? is there a walk-through i can look at?
It's frustrating; the car just feels so sluggish. I don't even want to drive it when it's like this.

Bleeding the clutch is a little troublesome. Bleeding the clutch should put the spring back into the pedal. When mine got air in it once, it would remain on the floor. It got a lot of air in it because I let the level in the brake reservoir get below the clutch pickup on the side (blue line) just below the top as I was pressure bleeding it.

Bleeding the clutch may solve the problem. If the problem is air in the system, but if the clutch is actually worn it wont help.

Spongy Pedal
What's up man? Long time no talk. Get yourself a flashlight and crawl under the driver side dash and look up at the clutch master cylinder. You will see an adjustable rod going through an accordian boot with a weep hole in it. If it's wet and your brake fluid is low, you've probably found the problem. Let it be known to all: A tell-tale sign for any Porsche when the clutch is bad-----the pedal is hard as a rock and doesn't "grab" untill the pedal is all the way up. A spongy pedal is either dirty/contaminated brake fluid, a leak anywhere in the clutch hydraulics, or a bad slave cylinder. Anyone who reads this post owes it to themselves to do this check, I'am willing to bet that some of your masters are leaking and you didn't even know it. PS-If this is it let me know, there is a critical adjustment procedure!

you can see the clutch master cyllinder through the driver's side dash?!?
So how do i remedy the problem if it is wet, and what does brake fluid have to do with it? And does this have anything to do with my accelleration problem? It just feels like there's no throttle response. I floor it in 4th at 3000RPM and nothing happens!

Yes, the clutch master cylinder can be seen from under the driver side dash looking up. If it's wet you need to replace it. The fluid feed for this hydraulic cylinder comes from your brake fluid resevoir-----as opposed to having it's own separate resevoir. If you're like most people the brake fluid in your car is the most neglected fluid of all even though Porsche reccomends routine flushes to prevent these types of failures and to keep the brakes from fading. The fluid should be transparent---not dark brown or black! You may have another problem though, the loss of acceleration is strange. Remember--if your clutch slips the tach will peg and the car won't move. You may have another unrelated problem?

driving my car again this morning, it actually feels like a throttle/fuel/air problem. When I rev in neutral, there is a little hesitation...and the response is not what it should be for my throttle imput.
Any ideas?

Your car only has 40K on it?
FWIW when I bought my car with 144K miles I went through the reciepts and the clutch was done around 98K so I asked around re: clutch life. Most people told me if you don't abuse the clutch it MAY last around 80K HTH
