Can any one help me plz im lost wot to do now

 

what car is it?
if its got a zetec engine in it, then its probably the idle control valve.. they always go on them.

 

Its a focus 1.6 on a 2001 plate should it not cum up on computer scan if its down people have said air leak but cud not see any wots best way to find air leaks

 

wont show up as its not a sensor... and essentially it is still working,
but its going too slow.

 

So is it the iscv and not an air leak because I dnt really no any think about these car and its doimg my head in wod cud b makeing it hunt and revs take there time to go bk down im just lost because of people dnt even no wot is wrong its doing my head in really need help and find sum one that nos wot they r doing

 

So is it the iscv is that wot u r on about and does it make your revs stay up for abit after u stop

 

Is the iscv wot u r on about then as iv not got a clue about these cars at all and really need help

 

Unfortunately it is a problem that without seeing the car its hard to diagnose

 

Im getting fed up with it now because iv not got a clue wot to do now

 

So is the idcv mean iscv other wise I dnt have a clue just want car fixed now its doing my head in well badly

 

Is the iscv the icv that he is on about has any one from kent got any they r saling

 

If it's not the air leak we have already discussed then the valve will be raising the speed? I seem to remember you have already tried cleaning it? Sometimes letting them soak in some detergent, i.e. petrol etc for 24 hours can do the trick, as the problem is with them they stick. Otherwise there are plenty around.

Im going to cheak again for air leak and get a new iscv no point getting secound hand one because it cud do the same but iv got to have my engine cheak because sum one said there is oil in the top of spark plugs but it cud of bin when iv filled it up but it does seem to b lacking power so im going to take spark plugs out and clean them and see if it happens again dnt want it to b head gasket because thats loads if money to have done

 

Won't be head gasket, this would have totally different symptoms!

If there is oil down the plug bores then you would have to of spilt LOADS of oil for that to happen! No point in cleaning plugs, easier and cheap enough to buy new, in fact far better to buy a complete service kit, and do your service at the same time! Plus this won't cause the hunting, they do suffer from misfires and the culprit will be the coil pack, assuming the rest of the ignition system is in good condition.

It looks like the oil is cuming from the top it looks to me as if its the rocker cover leaking I have got an oil leak on cambelt side of engine so got to have that looked at when get cambelt done. Im going to tri and find a iscv on ebay which iv had no luck in doing yet then will find out if its that if the iscv is playing up eod it play up all the time like when u start car and drive it and take your foot off throttle and it sounds like its hunting as well and los of power

 

Iv put computer bk on it today and there is no misfire so its got to b sum think ealse making it hunt Iv still got to find were oil leak is cuming from one is rocker cover and iv still got to find if its rocker cover leaking down from cams and not no seals on that side if there is any which I dnt no
