david75 has a point with very worn throttle body linkages. i do know which slider he refers to. its the white plastic coloured one in the "arc" slider at the side , where the spring is attached . they develop a lip / groove on themselves and stick if not cleaned out . lubrication only attracts dust and grime but a clean out might sort it if not too badly worn. for the cheap price i paid for an on offer part which included map and idler valve it was a no brainer. ..
