hunting tickover

I have a 2.3 saloon with nearly 100,000 on the clock, it drives ok and starts up every time, but when the engine is warm the tickover seems to give a little cough every few seconds. The problem has been there for six months or more so it isnt getting any worse..yet. but its enough to annoy me and I dont know where to look around a hot engine, without getting burnt. hmmm.
Do any of you wise sages know what this could be or do you think that I should give the beast to fords and let them play with my wallet 
I have a feeling that you are going to say that there is probably a leak in the vacuum somewhere. Ah but where. I have tried listening for some sort of hisss but with head under bonnet and engine noise covering up most other noises, fat chance.
Years ago, I had a hillman Imp with twin carbs which when not blowing head gaskits went like the wind. But I used to tune the carbs by listening with a length of timber one end on the carbs and the other wedged in me earhole...worked a treat  but for the life of me all I can hear with the scorp is engine. Just as well really, wouldnt want to hear anything else. Any road up, does anybody have a clue as to what is making the engine "blip" every few seconds? I do hope that you do.
Cheers Ferret
Oh highlander, the nearest town to where I stay is Montrose and the distillery is Fettercairn. I can recomend it

twin carbed imp eh? 10 years ago i had a twin carb wolsley, the bit of wood as a engine stethoscope is a great idea........for carbs, the scorp engine is far too complicated and is governed by electrics, and thats where i think most people would suggest looking (other than is the air filter clean?), i.e. is the MAF clean?
any members near you that can do an OBD scan?

also, use ford as a last resort, they'll probably take the car for at least a day, give it back when your bank account has been bled dry, 'borrow' a couple of cd's from your autochanger, then say no fault found...

Air filter...DOH! never thought of that one. I will put a new one in this weekend and see what happens. If the weather is kind then I will also get some switch cleaner and do the MAF. Is this an easy job TB? any pitfalls to watch out for? cos I am probably the bloke that the phrase was designed for."JESUS! that nearly had me eye out!....now where did it land?

Cleaning the MAF is probably the most simple operation of all. It's detailed HERE. Just be sure NOT to TOUCH the sensors you will see inside the sight tube. They are as fine as a bulb filament.Just spray again if they are not clean the first time. When you replace the air filter check a little 'pocket' at the back of the unit which should have a small piece of foam rubber inside it to filter the exhaust vapour from the engine. They are often neglected, rotted to 'dust',or not there. Worth a look.

Don't forget to refit the electrical connector when you put it all back together.....you wouldn't be the first !!.... as it easily hangs down out of sight.

Hi guys, as promised I would get back to you regarding the hunting tickover. I cleaned out the MAF as instructed on this site (good information) and as you said its an easy job to do. I also changed the air filter. The old one was very manky. I did have a bit of bother getting hold of one, cos halfords dont carry this item in stock (only special order) so I phoned up my local Fords dealers and picked up one on my way home on Monday. Job done. I have to say that the engine is running a lot sweeter..............However this annoying little hunt or clunk is clearer now and I am certain that this noise is comming from somewhere underneath. It is certainly a clunk when the motor is hot and when in neutral.
Now I am suspecting the drivetrain or propshaft kindoff catching up with its self, or am I talking danglers. I normally do.
Any advice would be very welcome........subject related

Hi, Propshaft and drivetrain will not be moving all the while the car is stationary.

have a similar issue with my idle, still getting to the bottom of it. i have so far, in order,
- cleaned MAF
- replaced air filter
- replaced spark plugs
- replaced IACV with 2nd hand one
- had a scan, replaced FPR (new)
- idle now "sticking" at 1500rpm for 10 secs
- fixed air leak caused by garage doing FPR
- no.1 spark plug blew, replaced again
- replaced IAT (second hand)
- back to stage 1, idle still hunting, now also sticking at 1200rpm for 10 secs
my next port will be injector wiring i think  or oxygen sensors.....
not sure if this helps, but is the route i took......sometimes better to leave sleeping dogs lie?

How confident are you of the second hand IACV?? Did you fit a new gasket? It sounds A LOT like the problem I had before I fitted a new IACV. I tried cleaning mine but it didn't do any good. I then tried dismantling it as far as I could and ended up destroying it, hence having to buy a new one! It did the trick but they ARE expensive 
May be worth cleaning the throttle housing and butterfly, sometimes the butterfly doesn't sit tight on the housing if it's dirty.
Good luck,
Graham

OK...how do i get to the throttle housing and give the little miscreant a d**ned good thrashing.....oh sorry got carried away there ment to say squirt of WD 40, just as satisfying really.
I love the smell of WD in the morning, son.
