Clutch problem or what??

[airFS]

Well my car has been doing this for quite a while and I'm starting to get sick and tired of it. I can basically be driving along at any speed and when i go to do any kind of hard acceleration it will beging to acclerate like normal but while it reving up it will make these thud sounds and you can actually feel them. There only for like a split second but it really slows the car down. If it's not doing this sometimes it wont acclerate right, i can be on a flat road but my car will almost act like its going up a really steep hill. The revs wont really move, the car just gets really loud and again my car wont accelerate. Please help me...ive got the need for speed!

Hmm, honestly from what you say is happening it sounds like your timing might be off abit. If the revs wont move or move really slowly when your trying to accelerate the timing belt could have jumped a tooth or two. It may cause the car to sort of thud or jump around abit while driving. But if you think it's something coming from the clutch then i don't really know what would cause those symptoms. Sorry. Let us know what you figure out.
