I was wondering if anyone could help me with this.

Car is an XR6 NA manual. This only has happened first thing in morning ie. cold start.

About 5 days ago I started the car, it kicked over, then stalled. I immediatley started it again and it stayed on but felt like it was running on 3 cylinders - VERY lumpy idle. Turned car off, restarted it - PERFECT idle, no problems.

Today - exact same problem again.

Car is running fine this arvo but I am concerned about these random cold start problems. I dont want to take to dealer as I am very busy - also dealer will just claim nothings wrong like they always do.

Any suggestions guys??

does it ever idle high?

like 2000 rpm?

could be a manifold leak or a loose breather hose.

If it has anything to do with the engine management system it would have logged a DTC.Sounds like it may have a VCT Phaser issue.If you drop in to your dealer and they have any decent technicians who know how to use a WDS they should be able to pick up any problems with very little down time on your behalf.Better to be safe than sorry.

I'd agree with Fordtech but also, make sure you don't touch the throttle on startup or you may generate an invalid throttle request and the PCM will set limp mode. (That's the 3 cylinder operation until reset)

Just another one guys, what does the car normally idle at?

I've noticed over the last 3 or 4 days that the idle is anywhere between 1200 and 2100 revs from turn on. After a while she finally settles down.

Still very happy but wasnt too sure

You have a Phaser Issue I believe....

Can usually be fixed by completing a RELEARN on the management system.

New UPGRADE avaliable will longer BLEED procedure for phasers on start-up.

Book in with your local dealer & have the UPGRADE done.

Should find this will fix the problem. :bouncey:

My t - ute had a lumpy idle from the day I picked it up until now some 13,000kms later. Upon speaking with a techie from Ford - someone I know and respect, this was his advice to me.

1. With the car off, push your accelerator pedal flat to the floor.

2. Turn the car on and then crank it over for about 10 seconds (don't worry - it will not start because with the accelerator being flat cuts out the fuel injectors)

3. Turn the car back off and release the accelerator.

4. Start the car as per normal.

What this does apparently is phases the cams in..... so I am told. BUT, it does actually work. My ute now idles smoothly - I was absolutely dumbfounded when it worked. Give it a go, you have nothing to lose.
