Problem.. Any Ideas Please

[whitelabelboy]

ill cut straight to the point,

rs200

something big's started rattling/clunking for around the first minute of driving, wether i pull off cold or leave it to warm up.

im going to go with.. its around the gear box area.

also the car will lose alot of power, struggle to rev up 'feels like the air filter is completly blocked' then go perfectly normal again, and vise versa.

if i hold the car at a steady speed/revs it feels like im blipping the throttle.

any ideas are much appreciated

thanks in advance

just been out and had a mess around, the clunking is definitely clutch/gear box related.. makes the clunking when the clutch is active
