Detroit 60 Series - Loss of Power

613124

{"text":"Truck has lost power, loss of MPG, can hear a fluttering in exhaust when jaking down a hill and start easing back into the throttle, best way I can describe it is like a choke on on an old pick-up truck? I originally was told that I had a restriction in the fuel system or getting air in the fuel system! I've replaced every fuel line and fitting on the truck, other than the restrictor fitting and the chevk valve! I've replaced both fuel filter housings, and fuel pump, everything was replaced with new parts! Still nothing has improved whatsoever!!! So then I was told I had to have a bad injector seat! So I then replaced a new head and 6 new injectors...Still no luck on fixing my problem or wallet I bought a new Air Dog Fuel System and STILL NO FIX! Between Detroit and Freightliner repair shops I could've darn near bought another truck or at least a couple brand new engines","pics":"[]","canComment":true}

{"replyTo":"","text":"if its a 14 litre with the variable velocity turbo.. it could be the sensors that tell the turbo what to do.  i had one and it acted like that.  i believe they called them the “v-pod sensors”??   they cost around $500 to replace if i remember correctly","replyToPid":0}
