Hi There,

My 1996 P Reg 2 .0 litre petrol has developed an idling problem ,it feels like the idle valve is partially sticking ,if it has one , Starting from cold feels like it has a fast idle and stays that way for a while then settles to a normal idle ,get to work ,no drama . If i start it again later on the revs climb to two thousand or so and it won't come down for a while . I've also noticed that sometimes the throttle will snap shut on the over run and the vehicle jerks ,and other times the idle will come down gently as it should . I've cleaned all the breather pipes and I've cleaned what looks like a throttle stop valve ? as both these items looked a bit worse for wear ,not having any workshop manuals on these vehicles makes it a bit more difficult . I've just done the o/s cv joint with no problems and other than the problem I've just described it's a good all rounder .Thanks in advance .:confused:

Remove idle control stepper motor and clean the housing it fits into. A can of carb cleaner will do the trick. Make sure ignition is off before removing it. There should be two torx 20 studs holding it on.

Sorry to be vague but is it black and round and to the left of the butter fly /throttle housing as you look in the engine bay ,and if it is then i have removed it and cleaned it and the hole it fits in and they were both filthy but the problem is still there . I have to say that before i cleaned these items i had a violent jerking issue that disappeared when i cleaned them but the idle issue is driving me mad .I have another idle control valve which i may try ,time permitting.:thumb:

Yes black and round. It is made by Magnetti Marelli. When you take it out take a look at the seat of the little plundger. Around the edge of it you will see maybe a shiny bit and then a sooty bit. The shiny bit is where it is seating correctly and the black sooty bit is where it is leaking air. Clean all including the throttle body.

Thanks very much Dave ,I have had this out and cleaned it but maybe there is a tiny spec of dirt stopping it working properly ,i have another one and i'll try this as well .It a shame Haynes or someone doesn't do manuals for these vehicles ,they are popular enough ,it would make identifying items a load easier ,I'll let you know how i get on sometime in the week. Many thanks :)

Hi Dave , Had a clean up today of said item and guess what ,the jobs a good en. I think there may have been a tiny bit of debris still lodged in there as the vehicle is so much better to drive and it seems smoother too ,thanks for your input and knowledge. see you on here sometime soon. Regards Chris.:thumb:

Hi, well it lasted a few days i guess ,i even changed the stepper motor but the fast idle is back with a vengeance .Is there a throttle position sensor or maybe a heat sensor playing about? Does this model have a diagnostic plug as i don't have planet ,and what is the sensor in the throttle body ,does this have anything to do with it maybe ? Is it worth taking the throttle body off and having a good clean out ,I've checked all the basic stuff such as sticking throttle cable and linkage etc ,no probs there and no air leaks as far as i can see.:confused:

You need to retrain the stepper motor.
Ign off, ign on for ten seconds, ign off for ten seconds. Do this a few times and it should learn.

Thanks Dave , I'll try it . I have just returned from dismantling the throttle body ,it was in a sad state so i got the carb cleaner out and basically gave it a good going over ,airways etc and reassembled ,it seems a lot better but I'll see what it's like in the morning . Many thanks for the info ,talk soon.:)

Cured 806

Hi Dave , took your advice and it seems to be running much better ,more control and generally more drivable and smoother ,in other words how it should be . My earlier thread i asked if these vehicles have multi pin diagnostic port , if so i have a code reader ,and where is the port ,or does it have to be Planet , how much ,and where from? as I've bought another 806 ,won't learn will i . I'd like to purchase some sort of manual ,whats best ,DVD etc ? Many thanks for your advice . Chris :thumb:

I take it all back ,started it up this morning at 04:30 to go to work and the revs stuck at 2000 rpm and it wasn't until i got to work 16 miles later that the idle dropped to 1500 ,the more i do to it the more it's gets worse . Anymore ideas anybody ? apart from torch it or ebay.:(

Work in progress

I threatened to take it to my local Peugeot dealers and hook it up .It seems this did the trick ,well nearly right i changed the stepper motor after cleaning it turning the ignition on and off and at the moment it's going fine so I'll reserve judgement as to what was the problem. I'm going to invest in a planet at some point so this may help.Thanks to those who responded.;)

Sorry to hear you problem is back. If i was you I'd get the stepper motor checked out. You need to get an actuator test done on it to see if it is excessively noised. If it is I would replace it.
Get a diagnostic check done and then come back to me.

Thanks Dave, Dare i say it but it seems to be OK at the moment .The problem may have been ,i bought a second hand Stepper ,it was all nice and clean and so was the one on my vehicle ,when i took the one off my vehicle i think i may have got it mixed up with the new on and refitted the old one ,I'm not sure, but it's running really well at the moment and is currently in a body shop having minor paintwork done .Once this is done it'll look pretty straight and then next month it'll be time to move it on ,only to replaced by a much later 806 . If the old 806 does start playing up in the meantime i won't mess about ,it will go straight into Peugeot's for a diagnostic check .I will let you know how it goes in the future. All the best and thanks for your advise .:thumb:
