xceptional Member 27 Member For: 15y 6m 22d Posted 20/11/08 07:37 AM Share Posted 20/11/08 07:37 AM Hi Just going through the advertisers forum and did not find any XR6T tuners located in Brisbane QLD.I have been having issues with my stock XR6T and Ford have not been able to diagnose the issue after two or three visits. I'm just hoping that a specialist XR6T workshop would know exactly what the issue is fix it straight away.Symptoms:After hard acceleration under full throttle, the motor runs rough (like on a lumpy cam) for about 20 to 30 sec when cold (running for about 2 or 3 min).Again under hard acceleration, after changing into third (between 80 and 85k/hr), it sometimes dies in the ass. Sometimes it feels flat and does not pull away until about 100 or 110k/hr. Sometimes it feels the same as hitting the limiter and does not accelerate until I take the foot off and press it again. And sometimes it surges as though there is feels like fuel starvation.There is also a quite a noticeable rattle from the CAT.What I have done on my own:Replaced CoilsReplaced PlugsReplaced Fuel FilterReplaced Fuel Strainer (attached to base of fuel pump in tank)Still the symptoms exists but has improved slightly.Some have suggested the TPS and or accelerator sensor. Others have suggested fuel pump, while still others the CAT and a download of the ECU to reset all the codes.Any ideas on what to do next or where to take it in Brisbane for a quick diagnosis and resolution.Cheers Link to comment Share on other sites More sharing options...

xceptional Member 27 Member For: 15y 6m 22d Posted 20/11/08 12:01 PM Author Share Posted 20/11/08 12:01 PM I have removed the heat shield so that's not the rattle - CAT it is.... Typhoon_freak, I live down Edens Landing area or not far from Beenleigh if you know that area better so anything in this area would be good. But I suppose I don't really care where the workshops are, as long as they are good at diagnosing/pinpointing issues, provide good advice and options, and won't stuff me around with unnecessary trial and error fixes.Blueprintturbo the vehicle is an 03 and out of warranty unfortunately with about 160k on the dial. It's feeling more like it's the throttle positioning sensor (TPS) but can't be sure. Apparently the early BA models had a larger TPS that according to a friend who used to work as a tech for Ford, should have had a recall, whereas the later BA and BF was fitted with a smaller (low profile) unit that seemed to fix a lot of the problems. I took him out the other night to a couple of industrial back streets and demonstrated the symptoms (where the engine felt like it hit the limiter and backfired around the 120k/hr mark) and he reckons a TPS but still not 100% certain either. Tonight had the whole family in the car going to the shops and while accelerating onto the motorway it struggled to reach the 140k/hr mark to change up to 4th (depressing). Before it would effortlessly breeze through the gears with a constant surge of power when in boost.How many big ones roughly would a dyno and a tune set me back? Already spent a bit as you can see trying to find the blasted problem. Very frustrated and annoyed. I miss the performance, but apart from that I love the car.Cheers Link to comment Share on other sites More sharing options...
