hi all at the moment i have a friends 206 and it is idling rough with the engine trying to jump out the bay! it also stinks of petrol and sounds like a tractor the problem does however go away if you rev it up but when you drive it, it just judders and you have to floor it for it to go anywhere im thinking it may be coil pack but i did remove this and test it and all the plugs fire i also changed the plugs which didnt make any difference, so im now thinking along the lines of throttle position sensor, crank sensor, or air flow meter has anyone else ever experienced this and know what the cure is?

any help much appreciated

scraps £150 a ton just now, cash it in quick

no seriously theres a common prob with these that could be at fault,
look at the throttle body(behind rocker cover where the coil pack is,
just to its left is a small multipug(3 wires i'm sure),
these are bad for breaking the wires going into them or bad connection on the plug,
when these go they run like a 3 leg'd elephant so try starting with that

thanks mate i will try that right now in fact illl report back with the out come

After checking out the multiplug, if you get no joy I'd turn my attention back to the coil pack. Checking for sparking plugs out of the engine is totaly different to a plug trying to spark when under pressure mate.....from previous experience I'd be throwing a new coil pack on it.

i just had a look and all the wires are still connected and not brolen i also dissconnected the plug and it looks to be in gud condition i did however try the car again after and it still running rough is there any thing else i cud try?

seen a 206cc exactly like this; we changed all sorts and it turned out to be worn tappets! engine had done 56k too

rostill2007

yes i also thought that this may still be at fault when experiencing proper load and am tryin to source one for tommorow at the moment so can retry it and go from there if it still doesnt cure the problem have you seen this before then and a new coil pack cured it?

rostill2007

this has done just over 60k i think will recheck it though and it does sound very noisy and another site i saw on the internet suggested this was it a hard job to do with any special tools needed or was it reletively easy?

Def agree with coil pack fault. Did you look at the old spark plugs when you took them out. Was one black or very clean an soaked in petrol?? Compression test??

rostill2007

i did think more towards coil pack because two plugs were jet black and badly fouled with carbon but the other two were perfectly clean

Yes, just last week Did an MOT on a 206 and just as I backed it out of the workshop it dropped down to two....try explaining that to the customer in reception Also saw a fair few of them whilst I was working at Peugeot (only there a couple months whilst they were waiting for a space to come up for me at one of their Vauxhall dealerships).

worth mentioning, 206cc will most prob have a different engine to this. Expect it's a 1.4/1.1 tu engine?

1. Coil pack - grey plug or white plugged
2. Injectors - recently replaced a set in a 1.4 and the piece of
loom. £500+ job with new parts. We went scrappy route for £60 and sorted our rough runner out a treat.

Good luck

check compression......... could be blown headgasket between two cylinders??

rostill2007

wouldnt fancy that tbh wud rather do what i did today and get a fone call explaining that there car has fucked up and they dont know what to do lmao i will deffinenetly change this tomorow if i can get one when im at work

rostill2007

i dont have a compression tester to do this and the plugs that were foule came out of cylinders 2 and 4 and the clean plugs from 1 and 3 so wouldnt of thought it would be between cylinders unless the dirty/clean plugs came from the cylinders next to each other cud be rong though

What Engine is in it ?
1100 cc tu ?
1400 cc tu3 ?
2000 cc rfn ?


Regards Doug .

ive had a lot of problems with number 1 injector . unplug it while its running and see if it changes on idle

rostill2007

its a 1400 mate on a w reg if that helps

rostill2007

i will try this if the coil pack does not rectify the problem

Doug

If the coil pack has squared off edges and not curved its an early coil and are seseptical to failure !!
Change coil pack and plugs and should be ok

But ! Just a word of warning when the coils fail they can have a tendency to spike the ecu and blow the out put driver for the coil pack rendering them usless ,
If this is the case no probs I can either supply or virginise another ecu for you that you can just plug and play without having to worry about key programming etc for the immobilizer or BSI matching .

Regards Doug.

rostill2007

how would i know if it has done this to the ecu? also i know some one else after an ecu for a 206 how much would we be looking at pm if you like

i used to work for citroen for many years (they use same engines, well are same company tbh)
i would look at as stated allready
coilpack, make sure you get the correct one the connectors on top are colour coded either white grey or black
also injectors do fail so would check those (a lot of people complain of tappet noise on these engines allthough it is usually the injectors they are quite noisy in operation)
spiked ecu caused by coilpack failure as stated above
plus another favorite is the flywheel sensor allthough these will usually cause it to not start allthough can cause a missfire too

i had a 206 it was the biggest peice of shit ever i must have rebuilt the dam thing it broke every week was as bad as a rs turbo thank god it got pinched

Here ya go matey!!!

To test coil pack. (primary resistance)

Ohms test across connectors 1 and 4 on coil pack (with plug disconnected) = 0.5-0.7ohms

Ohms test across connectors 2 and 3 on coil pack (with plug disconnected) = 0.5-0.7ohms

To test coil pack (Secondary resistance)

Test with ohms meter across ht/spark plug outlet 1 and 4 = around 21460 ohms, repeat for plug outlets 2 and 3.

These coils shit themselves for fun, if you buy a new one go for the Bougicord coil pack, Andrew Pages do sell these, so ask for them by name. All others are cheap crap and can cause more problems, especially ECU spiking!!!
