Hey all,
Recently purchased an 04 XR6T from Taree Ford. Put the boot in and starts making good boost till 4000RPM and starts coughing n surging , missing ....as if its running out of fuel for that boost its makin....and the boost is fairly up there...as far as I know car is stock...stock turbo, piping, cooler, injectors etc... unless some dipsh*t has put a generic tune in it...took it back to ford after hr later they said they orderd a new boost solendoid as it read out a code saying 'WASTE GATE STUCK' and also a new actuator...pressure tested the actuator and seems to move fine....so im waiting on parts...service manager says its ok drive it but try and stay off boost till parts arrive.... I said ill try but this problem is on your R/O and if it throws a rod out the side of the motor you are replacing the motor for fweeee....
in the meantime I ran the hose from turbo directly to actuator and it has helped...its dropped boost but still coughs and starts missing at 4000RPM....
which tells me the actuator may be weak.... fuel pump maybe?.....ami correct guys?... got no idea just putting it out there for someone who has had similar or has an opinion... TIA
