hey guys just got a m reg 94 cing 899cc got a running fault it will not idel at all unless you disconect the throttle postion sensor. engine mangement light is on it has a slight misfire reves up fine but feels lumpy its got new plugs checked ht leads and coil all look ok replaced injector stepper motor and tps still no joy any ideas. the only way to get it to idle is to keep the revs on

Map sensor or pipe compromised?

Cheers
