Doing my head in. Had the car 3 months and due to rough running took to PUG dealer. No fault codes . Cleaned throttle body , ran great for two weeks - now back to square one. Anyone know why ? Uses no oil , water etc. Crankcase hoses some emulsion but doesn't taste sweet ie antifreeze. Temp gauge reads 75C - is this a bit low ? (thinks crud building up due to low operating temp ?)
Thanks
