It ended up being the valve springs. but it could be anything the others have said also. Just telling my 2 cents. Link to comment Share on other sites More sharing options...

I gave it some through all gears to be sure and drove normal. I hope the issue is gone, time will tell! I am going to get a service done soon with CV Performance so hopefully I can pin point the issue and get it fixed get a dyno done and be sure its still running well. I hope its the valve springs, give me an excuse to buy a decent pair Link to comment Share on other sites More sharing options...

millers Member 113 Member For: 16y 8m 1d Posted 07/07/09 12:49 PM Share Posted 07/07/09 12:49 PM I have had the same issue for several months. fuel filter, plugs and throttle body have all been changed. have got fuel from a few different places so it shouldnt be fuel. it started out really random and seemed to get worse after a service. I have also noticed lately it seems to do it more just after the battery has been disconnected.I have got an error code of Throttle Control System Actuator or something like that which searching around for leads me back to a TPS issue.I received some more information about it tonight (info is from the BOSS engines, but I assume should be similar) that indicates it may be related to the oil used on the K&N air filter, which would explain why it got worse after a service. everyone says to clean the throttle body and try it again so ill clean up the spare one I have on my next day off and see how it goes.apart from that I have also heard that the throttle control module under the dash (the pedal) may be the cause of it. Ferntree Gully Auto quoted about $120 for the part I think, but apparently you need to pull the dash out to replace it so im not keen on doing that just yet.My car is an 05 BA2 xr6t. currently has 48000km and has been doing it since about mid 20000km.

Happening in any gear now. Its getting serviced by CV this Thursday so we will see what they discover.Will let you all know if we diagnose a problem and find a solution. I hate these problems, it could be a hundred different things, I prefer something to just break so I can get it fixed.Cheers Link to comment Share on other sites More sharing options...

Mine loses power after hard acceleration usually up hill due to traction control cutting in. It's pretty obvious because the TC light comes on but just thought I'd put in my comment. It doesn't happen when TC is off. It doesn't shudder though when it happens - sort of splutters for me. Link to comment Share on other sites More sharing options...

I spose that would be intermittent power, it would be general loss of power all round...? Link to comment Share on other sites More sharing options...
