its been a while ive completly forgoton to add closure to this mystery... Answer was.. Coilpacks.. Changed to a new set of coilpacks and presto. Problam gone. Thanks to Fertree Gully Autosalvage for all the help and advice they gave me .

JUST TO ADD, Check your connection from intake to throttle body aswell, some mechanics have failed to reconnect it leaving the rubber fold inwards beneath leaving it unsealed sucking in stupendous amounts of hot air lol... but yeh Coil packs switched and problem no longer there, now I can sell the car confident the buyer will have no issues doesnt hurt to check spark gaps too, I have no idea why it made my speedo drop but it is what it is.

Problem FIXED THANK GOD!!!!!!! with the help from the boys at Furntree Gully Auto Salvage I got 6 new coilpacks, replaced and now I can rev out no issue no loss of boost, I cant belive that's all it was!!!!! ford had no clue neither did the auto elecs or every tune place ive called had no idea...somehow having faulty coils didnt throw out codes but instead threw out random codes and disabled speedo O_o awell atleast the fix is here now on the forums!!!!!!!!!!!!!!!!!!!!! I hope the next person to go through what I did will find this thread!

and it did nothing..what in the f.. Could this be

real time scan showed comunication fail when on high load, now gona add earth to ecu and batt..

thanks mate, I got a mechanic goin to do a real time scan to see wat pops up, last thing I can do and afford now..

I just about had it, changed abs module, didnt make a difrence...code p1000 showing no one knows why or the cause, fml at the moment..

got a 2nd hand abs module for 280, getin it instaled today, hope it fixes it :( changed my sparks just incace but no prevale...dynomotive rekon these modules do this some cars they wrked on, throws out codes but nothin 4 a module..stupid thing, fingures crossed.

what about speedo dropin out?

I do wonder if its a loose wire? I have a strong feeling about the module hmmm do let me know asap moose what they find, or if any one else could assist us..

I cant belive no one else knows of our issue moose :( this is stressin me out, went for a drive last nite wen it was raining, as soon as it loses traction it goes nuts, I hope its a cheap fix..
