I can do most of my own work, although I cant do SERIOUS engine work or things like ball joints due to me not having a press.

BisB - what faults have you had?

CPS fault will lead to misfiring engine. I guess maybe on a xfire it will lead to serious misfire as the cynliners will be firing out of sync leading to the pistons firing at all the wrong times, bet it leaves to huge instability issues.
