Running with garbage power
Just got a 2000 excursion with the 7.3 in it ran great. Now it's running like it has ½ the power. But sometimes you'll be driving and not hit the accelerator anymore and it'll give you all the power back for a couple minutes and than take it all away again. Yes it leaks oil like any other 7.3 but there's oil in it and it gets topped up when needed. I've changed the air filter fuel filter and ICP (had oil in the connector). It does have an edge tuner in it don't know if that could cause the issues. I could go up any incline and it falls and downshifts, big hills I could start at 120km and I drop down to 60km to make it up. And now I am getting half the fuel milage where a full tank used to last 2 weeks now lasts 1.
I don't want to be throwing in sensor after sensor as that gets costly, so I'd like help on how to test different sensors and figure this problem out.
THE CODES:
Injector control pressure high
Electronic feedback signal not detected
exhaust pressure sensor A circuit low input
Integrated control panel circuit out of range low
turbo boost pressure low
turbo boost pressure not detected (pending)
there's soo many things it can be and I don't want to be throwing money to the wind to figure it out ,so any insight would be appreciated.

I was having a similar issue on my '02 F350 except the mileage loss, acceleration was sketch, about 2 yrs ago on Mother's Day, wife and I went down to fresburg to see the girls... went out to leave, started truck, put it in gear and nothing, no throttle, put it in 4-Lo to get out of the apartment parking lot, it would go then it wouldn't... played with the pedal, if I held it right it would work, kind of... got it towed home, pulled the accelerator assy.. the potentiometer inside was shot. Of course mine had the adjustable pedals and a rplc'ment was $800+ so I opted for the non-adjustable assy for $160... not saying that's your issue, just something to look at, 300k is a lot of movement on the pedal, mine was only at 150k..
