my vecrta 2.5 v6 (on a 's' plate) is running at 1500 rpms on tickover which i know is high, it just started doing it all of a sudden, any ideas on why? and how it can be fixed?
It is bound to be caused by a split or worn through vacumm or air pipe on the inlet side of the engine somewhere..? i would suggest either checking each pipe one by one or spraying a thin lube oil spray around each that way you will see it get sucked in by the engine and emmitted as a mild smoke from the exhaust for a few seconds or two..
