IDLE! idling and random revving increases and decreases

[gozzy-vtr]

ok heres it in as much depth as possible-

i start my car cold and it idols at about 1.6k rpm (too high) eventually after the idol going up and down it will settle at 950rpm (too high)

sometimes ill be sat at traffic lights or whereever n suddenly the revs wll drop to 500 then shoot up to 2.5k and then setlle back at about 950 again.

also my engine isnt ticking over smoothly k heres an example a normal car ticks over like - ooooooooooooooooooooooooooooooooooooooo

mine ticks over like 000o0ooo0o000000ooooooo00o0o0o00o00!!!!!!!!!!0o0o0 !!!!

coughing and splattering

whats the problem with it cos its not a good look really, makes my car sound like a right heap of shit

cheers boys (n gals)

[Banger_VTR]

could be a seal gone on the throttle body, the idol position sensor gone, need cleanin, or a hole sumwher in the air system

[s3tre2003]

haha nice way of explaining it..

clean the idol control valve?

[James205rallye]

MAP sensor?

[gozzy-vtr]

aaargghhh!! see theres so many things it can be, i dont even no how do hold a spanner let alone what goes on in a engine.. i can take it into a gargae but theyll probably stare into the engine bay and go 'yep, u need a new engine mate' lol!

"Idle" is the correct spelling ;)

Unfortunatly though like you have just realised there is a great long list of things which could be at fault, which costs enough for you to sort yourself, let alone pay a garage to have a field day replacing things!

If you can get hold of a diagnostics unit this might help to find the fault. Failing that i'd probaly start by carefully removing sensors from around the throttle body and checking for any obvious signs of wear/crap on them and where necessary arefully clean them.

Any sensor sending an incorrect reading back can have crazy effects on the engine due to the ECU trying to handle the information its being given as best as it can.

[gozzy-vtr]

ok mate sounds good, as i said i dunno how do hold a tool mate so,, what does a throttle body lookm like and what does a sensor look like LMFAO!!!

[gozzy-vtr]

help guys plz :D

[Brigbeale]

You need to get on a diagnostic machine first.
If any sensors are faulty, then they should show up and you can go from there.
Ring a few garages and ask them what they charge for a diagnostic test.
Preferably try ones which are Citroen orientated (smaller garages which work on mainly Citroens but aren't main dealers). Look in yellow pages under garage services and look for the Citroen badge.

[gozzy-vtr]

yea there barrets up canterbury 17 miles away ill try that, see whats goin on lol, maybe its broke n i might get forced to throw a vts engine in it aye lol

[gozzy-vtr]

???///////

[Keefo]

what RPM are Saxos suppose to idle at??

[rey]

mine does this, just had it on diagnostics today, and.... nothing :@ not happy, had the idle control valve replaced, cleaned the throttle body, all sensors are coming back fine, and it still splutters and occasionaly cuts out!

[David]

what RPM are Saxos suppose to idle at??

Just under 1k

ive noticed ive got a see threw pipe with alot of oil in it up to the seals and i dont remeber that there before my serice, think i may have a little blockage or somethin.

[gozzy-vtr]

:bump:

[stevo67]

The pipe sounds like the oil breather pipe take it off check it for splits etc,clean it & put back on.

yes it is that pipe mate, i need to take it off but its full of oil lol! surely thats seeping into my airbox?? hmm, its not ment to be there tho right??

[gozzy-vtr]

just reversing about my drive before i had a chance to break my car reved itself up and shot into the middle of the road! i didnt even touch the accelerator..

someone pleassse help

[gozzy-vtr]

this thread aint going anywhere,, ooook ermm hmmm

[badasssaxo]

try changing the temp sensor even if on diagnostic it says its ok, this was kind of what my car was doing revving itself and idle up and down and even accelerating a bit even though not pressing pedal, i had temp sensor changed and cleaned idle sensor now its fine.

[gozzy-vtr]

ok mate, its now idleing at 2.3k perenantly, gotta get checked

[JC-Furio]

Strange, hope you get it sorted mate.

My old 1.1 used to idle at just under 1k, then occasionally when sitting in traffic pops up to about 1.5k for no reason... but never affected the drive really.

[saxokid100]

Had the same thing,and it was falty map sensor matey!!.....

[RCD-Performance]

ok mate, its now idleing at 2.3k perenantly, gotta get checked

Change the following, in no particular order.

IAC Valve.
Cool Temp Sensor.
AIT (Inlet air temp sensor).
Map Sensor.

A leak in the inlet system may account for this, but its unlikely.

[gozzy-vtr]

meh, well if it unlikly its probably that lol! if it gonna hapen it'll happen to me ;) born with shite luck

cheers RCD, hope that aint gonna cost much, cos i dont have much

[RCD-Performance]

If you head and see me, i'll swap them all out one by one for a small charge and diagnose the fault, then you only have to spend whats needed :)

[Toad]

I spent weeks trying to figure out the exact same problem with my 106. It got to the point where the car started to misfire quite badly, so this prompted me to check the TPS. I pulled out the connection to the TPS and squashed the pins down so it made a much tighter connection. Touch wood, the problem hasn't reoccured, and it's been nearly a couple of weeks now. :y:

I changed the IACv and the coolant tempertature sensor, neither made any difference.

this is exactly the same with me. i have been trying to think of a way to describe it.

[Sophie123]

mine used to do it when it was cold.
made me look like a right chav sittin at ligts with me engine revvin at3000rpm.

i had the cooling sensor changed for something unrelated, and its stopped =]

[gozzy-vtr]

yea sat outside giving ym sister a lift to school and my car is reving itself lol. look like a right wally

[JoNaH_FTW]

yeh my car revs up and down when idle. Especially when the engine is hotter. Hasent got as bad as revving up yet, must be a problem in the design of the car if its quite common

[gozzy-vtr]

yea probs. or maybe its cos 99% of saxos get ragged lol

[saxokid100]

Also check your maxie fuses in the little black box in your engine bay matey,my idle was up and down all the time!! ive change the 80 amp fuse,and the three 40 amp fuses!! me motor fine now!!! i can drive it again,and enjoy......

[RCD-Performance]

It is very common we've found, a post comes up about bad idle almost every day, i shall wirte up an FAQ for it if people think it would be useful.

[Ben_L]

there already is one mate in engine section. i think every single french PSA manufactured car has an idle problem. fact lol.

[RCD-Performance]

That doesn' cover the problems with IAC, MAP sensor, AIT Sensor etc :)

[Mochachino]

mine does this now n again. About once a month, and it happended yesterday at 3 k revs lol. thought the throttle cable might have got stuck so lifted the bonnet n was all fine. Switched the car off and on n its fine!

On other occasion i start the car up n move off and as i changed gear with the clutch down the revs go up a lil bit but then drop!

And on the other occassion it dosent idle it just stalls :n: only happended once of each problem and only happens once a monthish lmao

[johnnyg_vts]

lambda sensor not been mentioned yet?

[oli999]

hiya m8 i had the same problem so i took mine to the garage yesterday. they did some special diagnostics testing, cleaned the throttle body and repelaced the map sensor my car nows runs perectly. it cost £140. hope this helps

[gozzy-vtr]

ok mate yea thats what everyone is saying to do

[keith915]

So did you get the problem sorted?

sounds a very similar problem to mine at the moment.

[bumblebeedan]

dunno if this is gointo help but mine is doing the same thing, it also sticks of petrol whn its warm which isnt good, but i just rememberd that for my mot i had to cable tie the fuel filter to the car, and as mine sounds like its being starved of fuel im going to have a look, will let you know whn ive done this and if it helps

so this is pretty much a pointless post but meh :fcuk:

[bumblebeedan]

fuck me just seen how old this thread is.....oops

did u get it sorted haha:homme:
