#1: Peugeot 206 engine Misfiring and Shaking badly Author: jimmy_fella, Location: LiverpoolPosted: Sun Apr 17, 2011 1:43 pm ---- Hi
Ive just joined the forum and have a strange problem with my 206.
Was fine when I went to work, parked it up, came back 6 hours later, started it and was misfiring and shaking badly, no engine light on. The breakdown fella said it was probebly the head gasket gone so I got them to bring it back home.
Ive changed the head gasket, checked the cylinder compressions and all are ok but its still misfiring and shaking the same way as it was before. Ive tried to get it down to a certain cylinder by disconnecting the injectors one at a time but there is no major change in the engine, also used a known dead spark plug in each cylinder but that was inconclusive.
Have tried to check sensors by disconnecting them one at a time:
Green coolant temp sensor(top of thermostat housing): Engine runs a bit faster.
Blue coolent sensor (under thermostat housing): No change
o2 sensor: no change when cold, slight change when hot.
MAP sensor: engine dies.
Air temp sensor (in throttle housing): No change.
Did not check throttle sensor or idle stepper moter.
Did a quick check of the coil pack and it gives sparks at the plugs, engine still misfiring even with sensors unpluged.
Is there anything that could be causing it to misfire and shake badly at idle.
Any help would be appreciated.
Cheers

Once it was back together again it was still present.
I good way i used to find out which cylinder was misfiring was to take off the exhaust manifold heat shield and then pour some water on the manifold and see where the water doesnt evapourate from. In my case was number 4 cylinder which was then narrowed down to a faulty injector. To double check i tested the resistance and sure enough there was a faulty injector.
My engine is a 1.4 8valve so its quite simply to do the above, not sure what yours is but i would suggest trying it the above as its quick and simple.

#4: Re: Peugeot 206 engine Misfiring and Shaking badly Author: imjeeves, Location: Glasgow / WellingPosted: Sun Apr 17, 2011 2:10 pm ---- Cam sensor is a common one. If you take that out it wont run well at all and eventually wont start

I hVe just had this problem with mine sorted!

Thanks for the replys.
I should of said its a 1.1 injection. When the head was off I did visually check the liners for damage but they seemed fine, also checked valves and the head for any obvious sines of cracks etc.
Will try water on the exhaust manifold to see if I can limit it to a cylinder, then fuel tank / filter, will then take the injectors out and test there resistance, will post back results.
May be connected or not, this problem happend not long after putting £30 petrol in at local station ?
Cheers

I had a vvid water noise in the passenger footwell of pumping coolant around the engine block I'd check again because you may skin your head ad it may no even need it!:(

My Dad but some in his truck, that started to play up... Turns out that the fuel station was watering the fuel down and it was causing problems...
#9: Re: Peugeot 206 engine Misfiring and Shaking badly Author: Edward, Location: In the garagePosted: Mon Apr 18, 2011 5:11 am ---- I ran mine with the cam sensor unplugged and it ran totally fine.
I removed all the injectors today, tested them with a multimeter and they all read 14.5 ohms. I put them back into the fuel rail, put carb cleaner in and used a bike pump to put some preasure in the fuel rail filled with carb cleaner.
Then with aid of a 12V battery manually turned on each injector one by one, injectors 1,2 and 3 sprayed great but injector no 4 was clearly blocked, spray was very weak and split into 2, did try to unblock it by reverse cleaning it but it was a no go, orded a new injector from local motor factors and got 8 new o rings off ebay. will fit and update tomorrow.
Testing the injectors in this way wasent the safest thing ive done, but hopfully ive found the fault.
Got new injector and fitted it today, engine now works perfect again.
Thanks for all your replys
Cheers

#13: Re: Peugeot 206 engine Misfiring and Shaking badly Author: kandlbarrett, Location: SwindonPosted: Fri Feb 01, 2013 2:53 pm ---- I love the fuel injector test that you did. not the safest but not high risk if you know there is a danger and keep the fuel spray away from you and any source of ignition. I will remember that one.
#14: Re: Peugeot 206 engine Misfiring and Shaking badly Author: V9977, Location: Athens, GreecePosted: Fri Feb 01, 2013 3:03 pm ---- That injector #4 always cocks-up.
Supossedly it's the drip from the screen washer jet but I don't buy it.

I've been doing this for quite a while and it works miracles.
I have made a simple mini-loom with button, psu and both types of PSA connectors used for injectors. Use gloves when doing this or bitterly regret it.
