#1: Sometimes really slow pull off Author: frenchfrog40, Location: MaidstonePosted: Sat Jul 13, 2013 12:30 pm ---- Sometimes my xsi decides it doesnt really want any power when pulling off. it normaly does it when you first turn the car on. You can have it in first gear with the clutch all the way up and throttle all the way down and it will accelerate VERY slowly and then suddenly the power kicks in. it only seems to be from a standing start aswell or rolling very slowly.
any ideas?

Stuck throttle butterfly sounds worth checking first. I was worried because I just replaced a broken lambda sensor yesterday and that didn't go away!

You need the fault cleared after replacing lambda sensors.
#6: Re: Sometimes really slow pull off Author: vmondude, Location: South WalesPosted: Sun Jul 14, 2013 12:00 pm ---- Yeah I did the whole shebang - BSI reboot and then ECU reboot. The management light and error display were still on for an hour or so's driving but then it cleared.
But today I removed and cleaned the whole throttle body, butterfly valve and all using carb cleaner. And although it seems to run smoother now, it still has the same initial pull away problem. No go at all unless you floor it and then it suddenly picks up like normal.
Very weird that it only does it on first pull away, once its warming up it's fine.
Could it be the plugs maybe? I have a sneaky suspicion that it would have NGK's in it if I looked.
Or maybe MAP sensor or throttle position sensor? Or maybe a choked up CAT after having a bad lambda for a while?

Hmm so not that then. Does it feel better though? I mean apart from the start up problem...
#9: Re: Sometimes really slow pull off Author: PugJH, Location: NorthantsPosted: Mon Jul 15, 2013 10:41 am ---- Check the coilpack, not sure which one has an issue on this model, Sagem I think.
I'm glad I'm not the only one with this problem though, I thought it was a dodgy remap, sometimes its a scary problem when you try to pull away at a roundabout, its like turbo lag on a diesel.
This weekend I'm going to clean and replace what I can to see what's wrong with it, hopefully clear the random flat spot.
Tell me about it! I used to get it randomly too, and yes roundabouts were like playing Russian roulette!! Only get it at start up now though since a good flush with high octane, BSI and ECU reset and the lambda swap. Might help you too maybe?
Thanks for the list, is that for the 1.6 though? As I see it says 110bhp and mines the 1.4, only 90bhp when standard.
#11: Re: Sometimes really slow pull off Author: PugJH, Location: NorthantsPosted: Mon Jul 15, 2013 1:21 pm ---- Yeah sorry the link was for the OP.
110 like mine.
I've given mine a flush but didn't seem to do anything.
I shall give the butterfly a clean at the weekend.
Although I thought maybe it was a signal problem on the FBW

I thought so! Yeah maybe signals, maybe it could be the coil pack...
#15: Re: Sometimes really slow pull off Author: peugeotgti, Posted: Tue Jul 16, 2013 7:06 am ---- Weak spark maybe coil pack as above?
#16: Re: Sometimes really slow pull off Author: kandlbarrett, Location: SwindonPosted: Wed Jul 17, 2013 5:07 pm ---- Only doing it on initial start sounds like throttle body still sticking or settling into a position where it sticks as it has been stood idle for a while.
Try giving a boot full of revs before moving off (either in neutral or with clutch down) to clear the initial sticking and after that pull away normally. If that initial rev pick up (in neutral or clutch down) is sluggish but the car can then pull away normally after that would suggest that the throttle is still sticking.
Alternatively remove the intake and get a mate to press the throttle while you look to see what the butterfly is doing. Get your mate to press it down slowly and see how the butterfly responds. Obviously this needs to be with the car cold.

Hi thanks for the detailed reply. I just took the whole throttle body off and cleaned the butterfly etc so I don't think its that.
Someone at work was saying today that this heat we're having could well be causing any air bubbles in the fuel line to expand causing a lack of fuel flow. Then when I floor it to try and clear whatever it is the pressure builds and forces it through!
Is there any way of getting rid of this? Oh and also would Redex cleaner actually clean my fuel filter as well? In case that's a bit choked up like
#18: Re: Sometimes really slow pull off Author: kandlbarrett, Location: SwindonPosted: Wed Jul 17, 2013 5:31 pm ---- There could still be electrical or mechanical damage that is preventing the throttle operating normally from the signal being given from the throttle pedal. I may be wrong but I still recommend you try what I have said to rule it out if nothing else.
I have never heard a car suffer in the way your mate has stated. maybe someone else here has but that is a new one on me in 30 years as a mechanic. Still open to learning something new though.

Yeah I thought it was reaching a bit, it's because he's having a similar problem with his z3 at the moment as well. I've always felt that the throttle is a bit iffy in this car, so I'm wondering if maybe the throttle position sensor or idle control sensor is faulty. But wouldn't that set the engine management light off? I'm only getting 32.1mpg at the moment as well according to the onboard computer and that's low for a 1.4 sport
#20: Re: Sometimes really slow pull off Author: peugeotgti, Posted: Wed Jul 17, 2013 6:13 pm ---- I cant see the redex cleaning the fuel pump.
it reacts with engine temperature and movement to work and clean properly..if your lucky..i wouldnt expect too much from the redex tho man.
As for the fuel filter just fit a new one there only about £9 new and will not hurt to renew at all.
Also for the air expanding in the tank this is unlikely as petrol keeps itself cool so high temperatures are just not present in the tank/fuel pipes.
Ive just read a similar thread with the same symptoms and he sorted his with a new clutch position sensor???this could be to blame???
If you notice there seems to a lot of cars having problems in this weather it seems?especialy the 1.4petrols for some reason?it would be interesting to find someone who really knows the 206 to find out what it is that is specificaly unique to the 1.4 206's and is not fitted to the other cars in the 206 range as it does seem that this running problem is found on only the 1.4 and only in the big heat we are having lately???
For you here i would read all the other similar postings and see if anyones added something that hasnt been suggested here yet and you might find the remedy...if you do then be sure to post it up and help the other 1.4 drivers suffering the summer stalling blues..

Ok interesting, thanks a lot for your input man! I think I will try replacing the filter just incase and check out the other posts. The clutch position sensor sounds like a possibility though from how the car feels so I think I'll look into that too! Thanks agin mate and I'll be sure to post the results for others
#22: Re: Sometimes really slow pull off Author: DREWDEN, Location: huddersfieldPosted: Thu Jul 18, 2013 6:42 am ---- I was gonna post earlier in the week, how there seems to be a lot of upturn in this problem, but quite frankly didn't want to appear like an idiot, saying the weather (heat) could be playing a part.
Sometimes strange ideas can spring up surprising results.
Brought back memories of the seventies, being a hgv driver, queues of lorries on the M62 hard shoulder, with fuel lines frozen solid, before they added additives to the diesel.
No mobiles in them days, great fun.

Hey would you be meaning clutch pedal sensor (instead of position) or throttle position sensor? As I cant find anything about a clutch position sensor for the 206
#24: Re: Sometimes really slow pull off Author: Timon2210, Location: PalestinePosted: Sat Jul 20, 2013 2:14 pm ---- well you should try to have a pedal resting using a pp2000,this only works for motorized throttle body.

Ha-ha yup! I'm exactly the same mate!
It's still doing it too. Even if you just sit parked and rev it to about 2,000 you can feel the engine start fighting with your right foot as the revs try to drop!
And if you let it, it sometimes stalls!
Plus today my engine light came back on again! About a week or so since I replaced my Lambda Sensor.
(Which is a really horrible task might I add!! )
Got a used but working MAP Sensor for a fiver on the Bay so hopefully that might make a difference! Worth a go for a fiver eh!
But this problem is really annoying me... although logic is telling me Throttle Position Sensor! ??
#27: Re: Sometimes really slow pull off Author: frenchfrog40, Location: MaidstonePosted: Wed Jul 24, 2013 5:18 am ---- at least you tried something, i ended up spraying some engine plastics and putting half a boot build in...

Yeah I'm always getting distracted too, I think it's a subconscious way of avoiding the real issues
So today anyway I put the replacement MAP sensor into the intake manifold and reset the ECU again. (sensor was out of a 307 but same thing)
Anyway the light went out but after a while idling, it started spluttering again and almost stalled itself a couple of times like before
It sounded like there was a pressure problem so I pulled the breather pipe off while it was struggling to idle and it suddenly spat a bit of creamy oil out from the rocker cover. And then it settled down!? So now I'm really confused... and worried it might be taking in water somewhere as well!!
Anyway I don't know what to think now, I just don't know enough mechanically!
I did read somewhere though, that it could be the PCV valve? That could be stopping air circulating properly and that the creamy oil is just due to my constant short journeys causing condensation.
That mean anything useful to anyone?
PS - I get a whooshing water sound in the car when revving up or accelerating straight after the first start. Could it be related?
#29: Re: Sometimes really slow pull off Author: vmondude, Location: South WalesPosted: Thu Aug 08, 2013 8:05 am ---- UPDATE
Ok so, as it turns out, my Head Gasket has gone!
The coolant chemical test went straight to green in a second
I hope this isn't what is causing the problem for you guys! As things are going to get pricey...

Only get it at start up now though since a good flush with high octane, BSI and ECU reset and the lambda swap. Might help you too maybe?
