MITCH-JOSH New Member 5 Member For: 11y 7m 30d Posted 25/03/13 04:25 AM Share Posted 25/03/13 04:25 AM Hi guys, I have a November 03 build auto xr6t with 170000 Klms, completely stock other than 20" wheels, as of late it has started to what I believe is overboost, feels like I'm hitting rev limiter and loss of power but it's no where near limiter, also as on Friday I experienced the engine light come on and it went into limp mode and upon stopping the whole car was shaking like as if the engine was labouring up, turned the car off and it started back up fine and I parked it and haven't touched it since then, I have done a little research about the what I believe is overboosting and every thread their hasn't been a definite answer wether it was plug gap or the wastegate actuator, coil packs or a fuel issue, I'm going to get ford to run a scan to see what the fault was/is but just am seeing if anyone else has experienced this and has an answer or for where I should look before I get a mechanic to touch it, thanks for your time Link to comment Share on other sites More sharing options...

F6RD Donating Members 249 Member For: 16y 2m 20d Gender: Male Posted 25/03/13 08:50 AM Share Posted 25/03/13 08:50 AM Sounds like the throttle body is faulty. I had the same thing happen to my car.You can either try and clean it with carby cleaner or get a second hand one from FTG Autosalvage for $80.
