For the last couple of weeks my car has been idling very rough on cold starts.Its more noticeabale when the the car is in drive and your stopped at the lights.There is a tremble through the car only when its diling though after about 10 minutes of driving the rough idle subsides.

Anyone have any ideas on what this could be?

I had a small varience in idle and a little tremble...and when I cleaned my throttle body and gave it a thorough service (myself not fraud) it stopped and I have a really constant and steady idle now... might help...

also do you let the car run a few minutes before driving or make sure you drive really babyish first thing to let the oil warm up.. this also helps...

Yeah I have cleaned the throttle body twice as I also thought this could be the cause...but it really hasn't made a difference

Thanks for the input though...

Mine is as an ex chaser also had it for nearly two years now and over all I have been very happy with it hasnt really skipped a beat...(curent idling glitch excluded...lol)

I have a BF MkII XR6T ex chaser that had the same problem. I had ford look at it while I was getting the diff bushes repaired. They have replaced the gearbox mounts which reduced the vibration a lot, however it is still there. Ford said it could also the engine mounts, as the constant on off power with police use wears them out. I am booking the car back in for them to replace the engine mounts to see if it fixes the problem. Got to love warranty.

Yeah mines a BF Mark II ex chaser also have had it for two years I actually have a mate that is a mechanic at a Ford Dealership...and this made all the difference to my warranty claims...there was no arguing and trying to prove a point if something was stuffed they would just replace it. I had my mate pull the whole driveline appart and re do suspension bushes etc...he had the car at the Ford Dealership for over a week...but this problem has reared its ugly head now that my car is out of warranty...not sure what I should do since I have already cleaned the throttle body...as most mechanics would point to that beig the problem...(a dirty throttle body)...It just does it for the first 10 minutes and then calms down...driving it...it drives very well but just that idle is annoying me...
