BA55Y Member 74 Member For: 14y 9m Posted 04/08/10 01:14 PM Share Posted 04/08/10 01:14 PM I have an 04 ba xr6 turbo manual and im having dramas with my idle on the car.Ill try explain an example of this as best possible for you guys to understand whats going on.If im coming towards a red light and ive shifted back through the gears into 2nd and im bout 20m from the line so I engage the clutch and roll up to the line braking my car will not hold idle, it will dip right down to 250rpm then go back up 750sih then back down again to 250 and back up to 750 and it will continue to do this until the car has come to a complete stop and isnt moving any more, then it will hold idle at 750ish with the occasional drop but mostly holds when the car has stopped. A few times the rpm has dropped right down to 0 and the car has stalled while rolling up to the lights with clutch engaged. It doesnt do this every single time I drive the car but I would say atleast 50% of the time now on a drive it will happen at some point. There seems to be no weather conditions that trigger it and the car is stock except for the typhoon lower intake been installed which I cant believe would be creating the car to have this affect.Im starting to think that turning on the AC makes the problem described above worse and trigger it to start happening. As I was rolling up to lights today with clutch engaged and I turned the AC on to demist the windows and the revs dropped right down to 0 and the car stalled. The car has not suffered any drop in performance and still drives perfectly well when its not doing this stupid idle businessThis problem has been happening for awhile now and its starting to do my head in. I dont really want to have to start taking chances at replacing parts guessing if I can avoid it but im not sure where to take the car to have this problem diagnosed. The fact it is kind of intermittent is also a pain in the ass because I cant swing past somewhere and show them because unless the car is doing it at the time I cant show themAny help would be great Link to comment Share on other sites More sharing options...

There are a few things that make those symptoms and the process of elimination can be pricey. Link to comment Share on other sites More sharing options...

Turned out to be the regulator on the alternator I think, something with the alt anyway. So took it to a auto sparky they replaced the reg and it was all good. Maybe take it in to an auto sparky and see if they can fault your alternator. Link to comment Share on other sites More sharing options...

I cleaned out my throttle body and it stopped it completely. Go and buy some throttle body cleaner, give it a good clean and hope that fixes your problem. It is the cheapest place to start and is a common problem with these cars. While you're at it do this: http://fordforums.com.au/showthread.php?t=67778&highlight=boost+solenoid+maintenance Throttle body clean will only cost you ten bucks and twenty minutes. Check topics started from other people on here and Fordforums, you'll see it has fixed many cars.I am also changing my coils today as idle is not completely smooth like it was when new...at least it holds a steady 750 rpm now though.

I'm still going with the coils and turning the A/C on will make it worse as it's putting more load on it when it's already struggling Link to comment Share on other sites More sharing options...
