Important! : Does this sound like a misfire? Oh and wtf are these....

22nd August 2012, 20:01

Hi guys
Car is feeling a little sluggish sometimes, slow to pick up
So I filmed the exhaust note
This is just after a clean so ignore the steam....

Sometimes you can just hear it drop a little bit - or am I psycho?

Oh and if you can't diagnose that, then here is one for you:
What the dickens are these...?

I wanna say llama/alpaca but their necks are deceiving!

Please help! Priority is the 1st one

Thanks

Mine is like this at the moment. Revs stay at 900 when warm, but every so often the car will drop like the video. Mines a little worse than this though I think.

22nd August 2012, 20:16

These are llamas. Don't get too close

22nd August 2012, 20:52

try changing the coilpack and yeah there llamas hah

22nd August 2012, 20:59

I haven't even read your problem.

Just had to post this.

22nd August 2012, 21:07

does it rev up smoothly? or sould like a lawn mower? quite hard to hear it on my laptops crap seakers. but sounds fine to me, mine does that occasionally.

It sometimes likes to blip the throttle itself too :/ and will bounce from like 500-1500...

Thank you, although the necks on these were crazy, giraffe style!

Yeah it revs really freely but sometimes when driving I will feel like it is nearly holding back :/

22nd August 2012, 21:39

Ok, I've looked at video now.

Dodgy idle can be ICV, it's common and easy to clean. Very good guide in one of the stickies, I think in the engine section.

The hesitation in driving could be a spark issue. Have the plugs been changed? If not, possibly coil pack.

Once we know a bit more, can suggest more possibilities.

Could be two problems going on, I'd suggest cleaning the ICV, changing the plugs if they need doing and trying some injector cleaner through it first.

Cheers bud will do that
ICV clean with carb cleaner
Sparks change
Injector cleaner
Fuel filter change

Then coilpack change if persists!

22nd August 2012, 21:42

I think there's a dodgy idle guide in this sections sticky too.

Shall have a look
But the weird thing is when that sounds like that the dials display a consistent 900rpm :/

I'll try those steps as said and report back

22nd August 2012, 21:54

Just for utter confusions!! :-)

Dude you killed it with a repost it seems!?

Ruineeeeeed.

23rd August 2012, 23:14

Having just driven, can say that the car struggles to pick up revs from 2kish but then will instantly come back alive
Possible fuel line problem?
Starvation?
Poor filtration?
Or spark problem?

24th August 2012, 09:46

Any other diagnosis
Gonna give the icv a clean today using carb cleaner and the guide
Then see how it sits

24th August 2012, 12:37

So just cleaned the ICV with wynns cleaner
worked really well from black and sludgy to a nice silver clean finish!
so fit it back in and went for an 8 mile + drive
car idled nicely, didnt struggle for power (much)
so i think thats sorted the idle lumpiness, next going to give a service so sparks, oil/fuel filter and oil change
see how it stands after that

24th August 2012, 13:01

try green temperature sensor for dodgy idle, was the last thing I tried but it worked.

How do you mean 'try'?
Get a new one?

24th August 2012, 13:09

Yeh replace it, only around £12 as well

Nice one
Will do the service, and a coolant drop then swap this too!

3rd September 2012, 19:25

Done a full service change
Oil
Oil filter
Fuel filter
Sparks
Gearbox oil

Still hesitant in 3rd! Feels like wind is blowing against it when cruising at 2/3k RPM!

I'm thinking coilpack next? As new spark plugs are in, and still happening!!

3rd September 2012, 19:57

Mine does this - and the EML says it's map sensor.

My idle only bounces low after I boot it.. and that's when the EML comes on

Mine doesnt even flash the EML!
And I've cleaned the map sensor as well! Grrrrr!

5th September 2012, 07:43

So as a full diagnosis of my issue
When driving, mainly gears 3 and 4, and a bit after starting the car so it is a little warm, but also when I've driven for a while
It feels like it is holding back/wind blowing against the car
Only between 2k and 3k with gentle throttle
If I plant it, it picks up and goes, but if I just rest at that RPM it feels hesitant/stuttering

I have changed:
Oil
Oil filter
Fuel filter
Spark plugs
And used a bottle of Slick 50 injector cleaner
All within the last week - problem still persists!

In summary, hesitant to pick up speed when light throttle applied in 3rd/4th between 2k and 3k rpm

Could the clutch be 'biting' and need slackening off slightly? Had the release bearing changed recently but was told the clutch was fine!
Does the throttle cable need some lubricant sprayed down it? Could be catching!?
Coolant related...?
Coilpack change?

5th September 2012, 09:09

Any ideas? trying to keep this fresh

5th September 2012, 09:10

I had a similar problem with my vts, It would hesitate at around 2-3k rpm.
Turned out to be the map sensor after changing near enough every other bloody sensor!

Sometimes the engine management light won't come on even if the map sensor is playing up, because the ecu is still getting a map reading, just an incorrect map reading.
Might be worth a try, they are £30 at GSF.

I think either going to be the map sensor, coil pack, crank sensor, or water temp sensor

Thanks bud
I will try them in the order above

6th September 2012, 15:37

I'm having the car put on the diagnositics test

the EML hasn't ever been on in my ownership, but always worth a look!

6th September 2012, 17:14

Code is coming back for the intake air temperature sensor
I'm adamant I don't have one!
Any help please!
Is it part of the map sensor?

6th September 2012, 17:41

Little grey sensor poking through the bottom of the throttle body

6th September 2012, 17:44

Mine does this, you can feel the car judder slightly traffic lights. And the exhaust puts.

The misfire im on about

Definitely doesn't Have that grey plug

6th September 2012, 18:24

Found it!! Problem on the way to being solved

One of the wires for the MAP sensor had snapped, I can only assume the MAP sensor contains the IAT, therefore that wire was for the IAT, bringing the code up!
I'm in the process of re-connecting the wire and we will see how we go!

6th September 2012, 19:53

Connected the wires back up
Seems to be sorted

Just gotta get the code cleared again using mechanics 3 grand snap on code reader :O
Think it tells you more about the car, than Citroen did when they made it! Haha
But at least it's sorted and can't believe it was something so glaringly obvious :/

11th September 2012, 17:28

Codes cleared yesterday
Had 2 regarding the decat/lambdas and the one about the IAT
Sorted the IAT and cleared the code, didn't come back on vehicle restart so think it is solved
Car hasn't felt sluggish/hesitant since - so JOB DONE
