#1: Judders trying to keep constant speed Author: my1st206, Location: Milton KeynesPosted: Tue May 21, 2013 7:22 am ---- Hi,
Having probs, 206 1.1, fine accelerating, fine slowing down, say I'm in a 30 zone and trying to stay at 30 the car jolts moldy, as son as I touch the accelerator it stops. Any ideas. Had 2 new injectors and no engine light is one, runs perfect apart from this.
#2: Re: Judders trying to keep constant speed Author: eddie206, Posted: Tue May 21, 2013 7:58 am ---- Defo sounds like fuel starvation...
Is it stalling and lumpy on tick over?
Can you see an inline fuel filter?if yes how much fuel is in the filter and is it clean looking?

Most 206 do not have a fuel filter as such.
It's a non-servicable integral fuel pump system.
#4: Re: Judders trying to keep constant speed Author: macca1411, Location: Westhoughton, LancashirePosted: Tue May 21, 2013 8:08 am ---- When was the car last serviced? Oil, filters, plugs?
#5: Re: Judders trying to keep constant speed Author: Sim, Location: West CountryPosted: Tue May 21, 2013 12:16 pm ---- Maybe it was implied, but what about juddering when in neutral?
#6: Re: Judders trying to keep constant speed Author: DREWDEN, Location: huddersfieldPosted: Mon May 27, 2013 2:26 pm ---- What gear are you in when doing 30, at a guess i presume 3rd, if you change down to 2nd and accelerate to 30
do you still get juddering.
#7: Re: Judders trying to keep constant speed Author: omricn, Location: israelPosted: Tue May 28, 2013 2:27 pm ---- +1 having the same issue the last couple of days
#9: Re: Judders trying to keep constant speed Author: eddie206, Posted: Tue May 28, 2013 5:32 pm ---- Hey there omricn...maybe you might like to hijack this thread as"myfirst206"must be too busy???SO...
does it stall and judder at all on tickover?
When was it serviced last?
what gear are you in on rattle...and
Does it still rattle in 2nd,3rd,4th?
Can you see an inline fuel filter?
Does it have the Bosch spark plugs?
What other speeds are juddering?20,40,50,60,70???
It will be good to continue with the thread incase others have the same problems with there pugs.
#10: Re: Judders trying to keep constant speed Author: omricn, Location: israelPosted: Wed May 29, 2013 2:03 am ---- Hey guys, thanks for your interest you are awesome I must say
well, lets begin the answering:
- I didn't get to replacing my spark-plugs yet but if I'll go there I think I'll go get bosch OEM ones from the dealership
- stall and judder on tickover - no stall, juddering a bit, sound from exhaust is "whoom-whoom-whoom" in one second intervals.
- last service about 4000-5000 km's ago (that's about 3000 miles), about 6 months ago. (sparks weren't replaced as they were in good condition)
- gears when feeling rattle - 1st, 2nd and 3rd, on low speeds, can feel the engine not getting enough air\fuel, and suddenly accelerating ok, and then a couple of seconds pass and the same behavior.
- can I see an inline fuel filter - have no idea how to check.. pardon my ignorance..
- spark plugs type - don't know, last time I saw them I didn't check, but I think so.
- car judders at speeds up to about 30-40 mph
IMPORTANT-
this morning I had some trouble with the car, seemed like it didn't get enough air\fuel, juddering, even stalled on me once when going from 3rd straight to neutral at a stop light, so I decided to stop by my uncle's garage, I described the symptoms, and suggested it might be related to the fuel pump or the spark plugs, he said he didn't think so, he thought it's more likely related to sensors\air, so he got a can of carb cleaner spray and sprayed into the hose connected to the throttle body while I revved the engine a bit, the juddering at idle then stopped, and I went for a test drive, drove it slowly, going from 1st to 2nd and 3rd and down to 2nd and 1st going no more than 35 mph - no juddering, idle is perfect, car didn't stall, drove fine all the way to work, including stop lights, heavy traffic, faster driving etc. so I'm going to pay attention to every judder and rev drop, I'll update tomorrow!
p.s also my uncle suggested to buy a fuel additive - Gold Label by Liqui-Moly and add it while I have about 1\4 of the tank, the car shop was closed so I'll get some this afternoon and give it a go.

I'm sorry the what?..
edit:
ok I know what tappets mean now.. but I don't think these could be related? correct me if I'm wrong?..

#14: Re: Judders trying to keep constant speed Author: MattS16, Location: Long SuttonPosted: Wed May 29, 2013 10:37 am ---- If the cleaner down the inlet improved it I would suggest taking out the inlet manifold sensor, small 8mm headed screw holds it in place, I've had no end of probs with these on TU and ET series engines, if the engine oil level is too high or even on the max in some cases oil vapor gets on to it and gives erratic idle and cutting out probs at junctions/lights clean this directly with carb cleaner and gently blow out, re-fit and see if that works, keep an eye on how high you top your oil up to also, if you can keep the level between 1/2 and max if this fixes it.
If its the TU5JP4 there is also a stepper motor reset procedure to stop it closing the throttle on return to idle, back in 2007 was a software flash to help improve.

#15: Re: Judders trying to keep constant speed Author: omricn, Location: israelPosted: Wed May 29, 2013 12:16 pm ---- Thanks allot guys you are awesome, Matt - great suggestions I'll be sure to give it a try this weekend and report back.
Meanwhile everything is a-ok, just came back from the gas station, filled her up half a tank and added the fuel additive, everything feels fine.

I believe the 1.6i is the 90bhp 1.6, as I own an xsi (110) but do correct me if I'm wrong..

OK, I always get confused what's what. I should stick to 1.4i only really.
Anyway, valve timing absolutely plays a role in mis-firing, esp. as the topic headline describes it.
However if you have 16V with hydraulic tappets (oil opperated) there's nothing that can be adjusted there.
#19: Re: Judders trying to keep constant speed Author: omricn, Location: israelPosted: Thu May 30, 2013 2:52 pm ---- UPDATE: so far so good, car drives normally, all is good
#20: Re: Judders trying to keep constant speed Author: omricn, Location: israelPosted: Sun Jun 02, 2013 2:15 am ---- Update:
this morning I was driving to work as usual, came across an old lady in a beaten up mazda, going like 10 mph, so I hit the gas, car went all fast & furious on me, amazing muffler sound, great improvement to gas pedal reaction, I thought I was imagining, so kept on driving, when I came to a clear spot on the road decided to give it another try, hit the gas, freakin' amazing, awesome sound and awesome acceleration. get this Liqui-Moly Gold Label stuff!!!

Sorry, I thought Liqui-Moly was some additive and I made that thread enquiring about additives recently because I was interested in people's thoughts and experiences with various brands.
#24: Re: Judders trying to keep constant speed Author: omricn, Location: israelPosted: Sun Jun 02, 2013 7:27 am ---- Oh, ok, yeah it's an additive, a fuel additive, a very good one for sure
#25: Re: Judders trying to keep constant speed Author: V9977, Location: Athens, GreecePosted: Sun Jun 02, 2013 7:54 am ---- Does the effect last after the fuel/additive mixture is used-up?
#26: Re: Judders trying to keep constant speed Author: omricn, Location: israelPosted: Sun Jun 02, 2013 7:56 am ---- Yeah sure, it's not the additive itself which does the trick, it's the cleaning of the fuel system that it performs. it's not like NOS. LOL

I'm not convinced.
Are you still on it or how long ago was it used?
#28: Re: Judders trying to keep constant speed Author: omricn, Location: israelPosted: Sun Jun 02, 2013 8:11 am ---- I added it two days ago, 1 container goes into half a tank of fuel. it's highly recommended by mechanics (ones I know and not the incompetent ones..). what it does is remove all the soot and junk from your fuel system, I've hard some people recommending the stuff but I wasn't impressed and was sure it's all placebo mambo jambo, but I was clearly mistaken, this stuff works.
#29: Re: Judders trying to keep constant speed Author: V9977, Location: Athens, GreecePosted: Sun Jun 02, 2013 8:26 am ---- OK.
Keep an eye on it.
I used Shell V-Power Racing (100 oct petrol + cleaning agents) which is meant to perform precisely this.
I put it on mine exclussively for about a year and ahalf. It went like mad with tons of torque, smooth acceleration, responciveness and surprisingly - was more economic (even though alot more expensive per litre) simply because it lasted longer.
However, I found it stresses the engine for certain using it all the time like that, and it quickly went back to normal as soon as I stopped using it. Valves didn't like it at all, but again this was constant use for an extended period of time.
It's obviously a lot more difficult to percieve the gradual 'fade' after it runs-out, than the step-improvement the moment you put it in.
#30: Re: Judders trying to keep constant speed Author: omricn, Location: israelPosted: Sun Jun 02, 2013 8:33 am ---- Agreed.. I'll keep an eye on it. also - it's not recommended to use additives persistently as you did, it will harm the valves (as you experienced) and basically every bit of the fuel system which is not made out of steel.. but I can understand wanting the car to feel as it feels after using it, it's kinda like drugs.. (though I never used any...!)
Anyway I'll update on a daily basis so I wont forget the first feeling the additive gave

#33: Re: Judders trying to keep constant speed Author: V9977, Location: Athens, GreecePosted: Sun Jun 02, 2013 8:50 am ---- This was not a one-shot treatment additives as such.
You're meant to use it all the time as it's a type of petrol eg. like straight V-Power (97 Oct + cleaning agents over here), and the additives are balanced supposedly to act as a v. slow constant process.
Regarding drugs I know what you mean.
#34: Re: Judders trying to keep constant speed Author: omricn, Location: israelPosted: Sun Jun 02, 2013 10:02 am ---- Well I don't know about other additives but this one clearly states "only use once per 10,000 km", I guess what you used was enriching the fuel octane?
And I have to say this - I'm having an out of this world level strange de-ja-vu right now
