Delta pressure feedback sensor, as in egr? No codes. when I test the egr valve vacume applied the motor stumbles. It is also getting vac signal from the intake manifold. The egr vac silonoid is good. The dpfs, how do you test that, three pins 5volt reference, power and ground. I'm not sure that egr is going to cause a fuel consumption problem.
