2002 Subaru WRX 5 speed manual. Whenever I'm sitting around 2500RPM for example and I give the car full throttle, the RPMs will shoot up to about 5000 with hardly any acceleration and then fall back down to 2500 and the car will then begin to accelerate. I'm thinking the clutch is starting to slip but could it be something else? Also after I let off the throttle sometimes the car will take half a second to stop accelerating. Almost feels like the throttle body is staying open for a split second after I release the throttle.

  • Is it serviced regularly and do you know if the clutch has been replaced at all before?

  • Yes it's been very well maintained it's entire life. I've only owned the car for a month but I believe it's the original clutch. Car has 300k km on it

  • I'd suggest you idea of a slipping clutch is right. I'd start prepping for it, as it's only going to get worse. Commented Oct 25, 2016 at 18:36

    Just for completeness' sake, I want to point out that 300,000 km is approaching the distance from the Earth to the Moon, which is a little over 356,000 km at closest approach (perigee).

When you get your foot off the clutch, there is(or rather said there should be) a fixed connection between your engine and your wheels. If you see a rise in rpm without the car accelerating, there is no other possibility than that the connection has slippage somewhere. And while the clutch is the most plausible option, i also think it's the only possible option. So i'd take a look at your clutch because to me, it sounds like its totally worn out. The only other option is that if you heavily upgraded your engine without upgrading the clutch. Then the clutch is simply not capable of handling the higher torque form your engine.

  • Yeah it's the original motor too so I'm quite sure it's just the clutch is worn out.

  • after 300k km it's not surpsising the clutch is worn out. Especially it its driven sportively much, which can absolutely be expected from such a car.
