Hi All I have a 05 RS with 119k on the clock. My car is jolts when I accelerate and sometimes it takes a little bit to engage the car to accelerate half way through its acceleration. Its like it stops accelerating. My neighbour said it could be my spark plugs or leads or distributor or maybe even my engine coil. Also my clutch has on occassion been making shreiking noises when I am letting it out to its engaged point during hill starts or to take off. Any thoughts on what is wrong? I am not really mechanically minded but I would like to be able top competently learn how to fix this issue my self rather than going and spending $140 on a diagnostic test. Also could you tell me what parts I need to replace or tools i need to buy to get the job done if there is special tools required.
