I have an 02 F250. I just got a waste gate control test fail code after getting in the throttle. And it makes a wiezing noise when warming up in the morning. Does anybody have any thoughts on this? I have a superchip tuner set at tow-performance and an air raid intake if that helps.
the wiezing is the EBPV warming up the motor, but that code, havent heard of that one yet.
just throwing thoughts out there, unplug the red wastgate tube and see if you still get the code. you could have a problem with the actuator that controlls the wastegate, its located on the front of the cac and has the red and green tube cooming out of it. just my thoughts.
