When it starts it make s a High pitched yelp... Turns over Ok and starts fine enough just this high pitched yelp/yowl.... Now said mate bought it of their mate.... Prior to the sale this mate of my mate had complained of bad fuel consumption... He had a mechanic out who diagnosed bad Lambda not before discovering a badly split Inlet/Air Pipe and bodging it. Car keeps cutting out whilst cold , apparently better whilst warm.... I don't know. Still makes this yelp and cuts out whilst code... I'm thinking CTS Is at fault + a whole world of other ****?... Anyone have any exp/ideas? TIA
