I have a 2001 F250 7.3. I can’t go slow in it. When I step on the throttle from a stop it’s very delayed and then will all of the sudden kick me back in my seat and take off. It doesn’t do it at high speeds however. In neutral if I step on the gas it does the same things with the RPM. If I hold the pedal in one spot it will jump up or shoot down out of nowhere. I have replaced the fuel filter. It has thrown a code for exhaust back pressure for a long time. That’s the only code it has. My next step is going to be to replace the EBP sensor and tube. If that doesn’t work do you guys have any other ideas? Thanks
