id say one either the pcm lost the vgt strategy (assuming you have the inferred EB recall) or the turbo is sticking. to reset the vgt strategy you really need a ford scanner to verify whats going on but you should be able to without it. disconnect both batteries for approx 15 minutes to erase the keep alive memory, reconnect batteries and drive it to get it hot EOT should be at 185 degrees atleast. let the vehicle idle for 10-15 minutes. if you listen to the exhaust you should be able to hear to tone change every few seconds. that is the vgt in the turbo opening and closing the vanes. it needs to cycle from 10-100% atleast 5 time. thats where the scanner helps out. once the tone stops changing it should have learned the vgt strategy. if did not help your problem any then yeah it sounds like the vanes are being bound up inside the turbo and it needs to be cleaned.
