Ok I own a 01 cummins I bought it a couple years ago but ever since I have had it the idle has been high I read a lot of forums about it but now I'm going to get a thread going to talk about this to help me out it idles around 900 to 1000 rpm when I'm just sitting when I shift the Roma don't go below 1000 rpms now I want to know if this sounds about right to any one? This is my first diesel so I'm use to gas engines not diesel I want to know if there's a possibility the guy I bought it off took it to a dealership to turn the high idle on or if they just run that high I put an aurora 3000 turbo in it I've got stage 3 ingectors aftermarket air intake torqued heads on not to much done to it but let me know what you guys think
