Customer Question

Have an 07 GMC duramax 210,000 trouble free miles just started surging at idle will level out after a minute or so got a low fuel rail sensor code now it starts fine but can not get over 1400 rpm. not pulling a load. Once in a while it will start to run right but it will always surge as I approach idle. I did rebuilt fuel filter houseing thinking a fuel leak but no change.
Looking for ideas. Love the truck have had a banks chip, exhaust, and intake on it since new..
