So I've had my OBS CCSB for a little over a week now, and it's getting terrible milage. And I mean terrible. It's a K2500 5.7L/4L80E with 4.10's but I should get more than 180 miles to a full tank of gas.
The truck starts very easily, has no codes stored and the engine light is not on. It idles smooth, the air filter looks ok and the coolant temperature sensor is within spec. Any ideas where else I might start? I have not had a chance to check plugs/wires/cap/rotor but they look fairly new from the outside. When the weather clears up I'll check all of that. I'd suspect the MAF sensor but I'd doesn't have any of the normal symptoms, aside from the aweful milage this truck runs beautifully.
Any help would be great. Thanks.
