Is that just since you 'tweaked' the pump, or was it always that fast?swiss wrote:Mine idles at 1125... 1175 first thing on a cold morning

The HDi idles the same wether cold or hot.
Sometimes it can idle high but if you wiggle the multiplug on the throttle position sensor it settles down again (this botch is courtesy of Puggy
