Hi, can anyone help me with this one. My 2002 p12 2.2 diesel doesn't seem to accelerate at a steady rate all the time. It seems like I have to accelerate hard for it to go, or keep it over 2500 revs. I've never known it to be any different since owning it so I can't compare it to how it was. It's done 107000 miles. Thanks for your time with this.

have a 2004 2.2 diesel losing power happens while driving i have to switch engine off and on to reset ems. happened 6 months ago at that time dealer reset setting with computer. the problem disappeared but is back with a vengance can anyone help
