Hi i hope someone can help me, i have a slight problem with my car.
When it is left to tick over it sounds as if it loses revs and then bumps back up sort of as if it is missing although on my clock the revs do not go on. After a while of just standing the happens every 30-40 seconds. Its really starting to bug me now. i wonder if anyone would know what type of thing could be wrong so i could explain to my dealer a bit better?

Mine has started doing the exact same thing recently. It's really irritating, I agree!! I took it to Ford on Saturday and apparently they couldn't find a fault with the engine and I was told to go back should it get worse <_< I'm not convinced though...

Someone mentioned it could be spark plugs or maybe the coil pack, but seeing as I'm not mechanically minded I wouldn't know how to go about checking these things, let alone locate them in my engine :blink:

I have this problem, me and my dad adjusted the spark plugs a couple of weeks back, and it got better, for a few days... The problems deffinately got worse. Like you it started with the occassional shudder, uneven idle etc. Nowadays it's constantly can't sit still on idle, and it shakes the whole car! When driving slowly it actually affects the speed, which is very uncomfortable/embarrassing in traffic.

Tempted to change the spark plugs, because adjusting them really helped, but shopuld a car with 13,000 miles really need new spark plugs?

I guess I'll take it into Ford and see what they say, they can't deny a constant fault, surely?

Oh, and my fault has recently developed to complete power loss, happens occassionally, change gear and put foot down, nothing, Revs just drop all the way back to idle. Not sure if this is related. But these 2 faults are really ruining my first car experience :/

Sounds like EGR or the Throttle body breather issues that you used to get in older cars. I used to have similar issues with Vauxhalls. A right lumpy ride they were when they got clogged with all the carbon crap.

Thanks, I'll mention that when I take it in.

Report back and let us know what happens. Details to give to dealers can be useful for anyone else with similar issues. Good luck.

My car is in for a service as I type this. I have the same problem and it is on their notes to look at. Somehow I don't think they will find what I causing it if it doesn't show up as a fault code. Fingers crossed and I will report back later or tommorow.

Mine (Titanium but with the Zetec S engine) has had an intermittent "cutting out when driving" issue from 3 months old - & surprise surprise, 2 different dealers both "unable to fault". Have also noticed too the issue where now & again revs suddenly drop at idle, engine almost stalls then revs go back up to normal tickover speed.

I'm glad I'm not the only one with this problem tbh.
So everyone with this fault are all running the 1.6l Ti-VCT engine?

Just an update from my service. No fault codes were showing so the issue remains. Sometimes I do think dealers rely too much on sensor codes but I guess trial and error would take too much of their time.

Just a thought, does this show on the rev counter when this happens? If so then I would get a friend to video this with a mobile while you're driving & show it to the service manager at your dealer.

What type of fuel you using?? Long shot but my diesel developed a stutter as tho about to stall after 15-20 minutes. Stopped using shell, problem gone away.

I've take a video of the shuddering on my phone, lost it now, that was only when it was intermittent, it's constant now! I'd like to see them tell me it's normal. When I take mine in, I'm not going to be accepting mine back til they find some sort of resolution!

Personally I fill up all over the place, Usually Morrisons or Texaco, which use the same fuel. But I've also tried Shell and BP and the problem persists.

My engine is losing power a lot more regularly now. 3 Times in one night, over about 40 miles. The one time I let it go. 2nd gear and about 20mph, foot about 1/4 down the accelerator, sure enough the revs just plummeted til the car stalled. Changing gear or putting my foot down hasn't failed me yet though as a way out.

If you still have the original spark plugs fitted change them they will be cheap and nasty and you wont find 2 with the same sparking gap. get a good quality set from bosch supper pluses or champion which are pre gapped and will stay correct for thousands of miles. also worth checking if the air filter has ever been changed or the fuel filter as these often get overlooked.
