hi all my engine is puffin on tic over, any iders

Pauls,

1) your Ford model shows "not gone one yet" so more detail is needed on what car / engine / transmission / fuel etc.

2) can you define "puffin on tic over" -

is it making a puff noise like a genie in a lamp?

is it puffin' gas out the exhaust pipe in plumes of black smoke every three seconds?

is the bonnet blowing open and then closing itself because the engine is puffin a high pressure explosive air out through the spar plug heads out forcing your bonnet to explode?

You need to provide more detail than you have, otherwise most members will skip the thread and ignore your plea.

more information definitely needed, if the engine is coughing, I once had a problem where water was getting into the distributor

at that mileage did anyone think to check the fuel filter first? its the most looked over part as its considered to not need changed but they do puffing is a broad term a muffled pop would suggest overfueling however my old 1/8 did the same and it was a charecteristic of the engine seen escorts do it also its suggested that the low idle and the fact fuel doesnt burn consistently can cause a slight almost puff sound if its not loud and the cars running fine no smell of fuel from the exhaust once the cars up to temp ide except its just the low idle

all the vacuum hose been checked for leaks?

Definately start with the Fuel Filter and the fuel filter housing. Whilst the engine is idling, if you pop the bonnet, and then get to the ground near the rear wheel, can you hear any unusual noises from the rear wheel, slowly crawling forward to the engine bay, and finally under the bonnet? if you can hear any sort of "resistance" in the path from the back (sort of like the fuel is trying to squeeze through under pressure, then you can definately look further into the filter.

When was the last time the Fuel filter was replaced according to your invoices?

hi thanks for all your replys

i dont no when the filter was last done ,but if its any thing to go buy the air and pollen filters were black, So I will change it over the weekend and let you no if that has stoped the puffin,

Thanks again and what a great forum :)

Hi all

Ok fitted new fuel filter no change :(

so my new question is ware is the Idle Air Control Valve and what do i have to do to take it off and fit a new one (pic's would help) :D

I believe the ICV on the 1.8 is at the rear of the engine and quite tricky to get at.

Hi and sorry but is this the right one for my car

yes its on the right behind the coil pack easy enough to get to

hi all thanks for all your replys BUT its still there, i have changed the fuel filter and the idle control vave but its still puffin, could this be when the cambelt was done ,not been put back propley maybe a tooth out ????, if so how can i check it

you cant its impossible to get the timing out if iy was done at fords with the proper lock tool

Hi and thanks for the reply well i don't think it was done by fords i have no paper work for it , the man i got it off said he had it done, if its not that what could it be ??????????????????

also the reves go up and done as well ,on tic over the car reves low and once you come to a stop the reves stay at about 1500 then drop down,

any iders

Hi and thanks for the reply

well i don't think it was done by fords i have no paper work for it , the man i got it off said he had it done, if its not that what could it be ??????????????????

It's quite easy to screw the timing up if the locking kit isn't used correctly but I'm sticking with a vacuum leak or a split hose..

Hi. Ihave 1.8 '99 petrol zetec and share your problem with 'hunting' at low revs and occasional stalling, New Quality HT leads and plugs with correct gaps set seemed to sort the first time. iac valve the second time and lubing the throttle cable and now I think its just part of the focus make up. I'm having a play with a slight misfire now too so will let you know if its connected. Also try not to use supermarket fuel definatly makes a difference in the running.

hi thanks for the replys ,

could it be the airflow meter, or the cold start staying on ???? as im useing a lot of petrol

£20 and i get 96 miles :(

What happens if you unplug the maf sensor? A duff one will cause running issues...

Big thanks to stef123 give that man a cegar it is a air leak ,but i dont no ware it gos so help ,

TRY to the left of where youre hand is a black circular box it fits there by the look of it or behind the engine where ure hand is in the picture it will conect to a larger piece going into the engine next to a rubber hose with a bend in it that runs under the coil pack

Thanks Arthur thats a great help

Do the revs hunt when car has been left for couple of hours? sounds like it could be cylinder head temperature sensor;not an expensive fix.
