just fitted my tsr cam and jetex exhaust, all was well, runnning sweet as, unti i puled up at some lights, it felt like there was a clicking on my clutch pedal, then as i pulled away the car sounded like it was running like a dog! pulled over and i can only describe the noise as if it had ost compression, but the engine is sweet, stil revs up perfect, idles perfect etc, just sounds like a bag of bolts! am i likely to have ruined my third box in 6 months! or coud this be clutch failure, the clutch pedal is fine, i wil be rather hacked off if its the box again! can anyone help....
