HIGH TICKOVER
« on: August 04, 2016, 12:01:52 PM »
My 2003 2.3 galaxy auto has a high tickover speed idles steady at 1200  rpm which i feel is to high
it does not run lumpy or uneven and drives fine just that with such  a high tick over she moves which in gear and you have to hold the brake this is not normal but i cannot see how to adjust the tick over any ideas folks
i should add i have tried a new air mass sensor

Could be (among other things) a worn or dirty throttle body or a gummed up/ weak throttle return spring,  possibly there's something in the crankcase breather system on these engines that fails possibly causing rough running/ idling but I don't think it would cause high idle, needs somebody else to chip in here as I can't recall what the issue was.

Cheers for that but have cleaned and checked breathers etc vag diagnostic shows high idle but wont let me slow it down car runs sweet no roughness of lumpyness at all and its only done 45000 miles
bit of a puzzle in the old days you would just turn the revs down on carb but today its all overcomplicated just wondered if it was common fault

What's the condition of vac hoses as one of these being split/disconnected will cause high idle.
There is a rubber vac hose behind exhaust manifold prone to perishing from heat.

Did you check the PCV valve when you cleaned breathers? My old e46 bmw used to suffer with high idle that turned out to be clogged valve and split hose from that to block allowing air to enter and then get in to the intake. Not sure where it is on a 2.3 Galaxy though?

new hoses fitted a while ago checked them and pcv valve is new i have been over engine with a fine tooth comb there are no mechanical issues at all the fault is electronic looks like i will have to hack into the ECU and alter software there should be a way to adjust idle revs in software my audi has a way and  so did my old passatt so i can only think fords software is inferior

Are you sure there's no possibility of the throttle body being worn/ gummed up? If the butterfly isn't seating properly or the housing is worn allowing more air to pass through than should be able to with a closed throttle this could affect your idle speed.

Positive have checked or replaced every mech part as i said there are no mechanical issues as an engineer of over forty years experiance i am sure its electronic

this is my first galaxy it was bought because it seemed to fit my needs but it will be my last
never had a car with so many faults

Has the idle always been that high or has it started recently?

There will be an adjustment in the ecu for idle speed but I am going to hazard a guess and say specified and actual idle will differ when checking the settings. The ecu can only control the idle based on sensor readings and the vac side of things being sealed. If there is an issue with vac leaks be it from a pipe or manifold gasket or problems with idle control valve,throttle flap it will not be able to be it down.
Unless someone has already been messing with ecu idle adjustment I cannot see it being ecu causing it.

My old Ford databook states that idle on the 2.3 petrol should be 875 rpm.

Being that this engine unit on the Galaxy still has a mechanical, cable operated throttle, I cannot see how the PCM could raise the idle speed by over 300rpm compared to what it should be unless there is some other fault.

on an unloaded engine I think there will be enough movement in idle control valve to raise idle by 300rpm. On a similar set up with Vauxhall 1.8 and 2.0 xe engines you could raise it by about 500rpm using tech 2 adjustments.

I don't believe the problem with this 2.3 is an electronic one though,I feel there must be a difficult to trace air leak somewhere,I think the 2.3 has got a lot of vac pipes to go wrong.

Correct me if I am wrong but isn't the cruise control done by vac and that is hidden away somewhere? Could that be a potential cause?

The cruise control works with a separate electric vacuum pump so not the vac from the inlet manifold.

A few thoughts:
Possible problem with the gas cable so the butterfly valve doesn't close totally. So you can disconnect it and move the valve manually to check

There's also a vac line (at least on my mk1) that runs to the back of the car to a valve for the coolant lines for the rear heating. You also checked for leaks over there? this vac is controlled by a electrovalve on the bulkhead that you alo can check.

Thanks for all the advice folks but none of it helps i have checked everything and there are No leaks or sticky throttle and car does not have cruise control i have full vag software but it does not show any idle adjustment for the 2.3 engine only the tdi and 2.0 so am lost

VAG / VCDS software will not communicate with the 2.3 petrol engine management as it is a Ford engine / PCM / engine management system. You need something able to communicate with the Ford engine management.

For testing purposes can you clamp off the breather pipes where they enter the inlet? Also can you clamp off/blank the vac pipes where they enter the inlet?
Don't forget about the brake servo take off hose can you blank that at manifold?
Also have you tried spraying some carb cleaner around inlet gaskets and vac hoses to see if idle changes?

I still think there must be a vac leak somewhere to cause such an increase in idle speed.

Failing that you need a scan to check sensor readings especially coolant temp,maf,map and egr.

SOLVED!!

Visit to local friendly ford dealer reveals  you can't use vag software as quote "its a ford" couple of minutes on his laptop and bingo perfectly smooth tickover at 800 RPM  i knew it was electronic fault not mechanical been an engineer for forty years so i know the differance also ford software showed several fault codes all now cleared as a bonus i now have a copy of the ford software cost me a few pints though but happy days
Am slowly growing to love my galaxy but i still think it was designed by an idiot!!!!

Sorry thought i said ford software gives you a range to set the tickover he just set ecu to 800Rpm and away it went and before anyone asks i already said i have an odd galaxy as none of the stock faults apply mine does NOT have a throttle cable its an electronic throttle also going by the engine number i      dont think its the original engine!!

It certainly sounds like you have a non standard set up going on if egas throttle body is fitted?!

The build is still somewhat better than some other Fords I've worked on though! In particular, VW have a tendency to use a zinc type paint or coating over the majority of their fasteners which means that after a number of years you can still get them out as they've not rusted in solid!

On the other hand, I fail to understand why VW persist (unless they now use a different process) with applying surface finishes to plastic items such as door grab handles, fascias etc which get handled lots in use, as the finish starts to wear off after a few years and looks crap- my partners Touran exhibits this with the door grab handles, external door handles (not body coloured), rotary light switch and stereo fascia all suffering from it. Why not just use plastic which is the correct colour all the way through so doesn't require a surface finish which is liable to wear off, especially on items which get handled in use?

The Touran is also suffering badly around the rear number plate lamps from rust, which is something I will have to sort at some point. I've also just replaced the rear damper bump stops because they're made of some type of (I'm assuming) polyurethane foam which loses it's strength after a number of years and just disintegrates, though to be fair many manufacturers use a similar setup, not just VW.

So I'm not in total agreement (if the Touran is a fairly typical example) that general VW build is better again than that found on the Mk2 Galaxy / Sharan etc.

My galaxy has the dreaded tacky finsh on door grab handles and dash which has all worn off was going to carbon fibre it but will see right know am looking for  another 7 seater as galaxy/sharan/alhambra all suffer with a big problem in that once all seven of my family are in theres no where to put luggage!!!
as  i bought it to take my family on holidays to spain its not much use and i dont like roof boxes or trailers
so its back to the drawing board
