#1: Throttle killing engine and running rough Author: JoeMc96, Posted: Tue Apr 21, 2015 7:29 pm ---- Hi just wondering if any of you know what's going on with my 206. It is running a bit lumpy on idle and when I get the bite to move off it kills the engine and sounds and feels awful. Just had a full service to see if that fixes the problem but unfortunately not. Had diagnostic returned nothing . No lights on dash. Just bought the car on auction site hills only very minor cosmetic damage. Engine is 1.4 16v.
Any replies would be appreciated.
Thanks

Gummed up VVT solenoid - give it a clean.
There have also been several software updates - Peugeot main dealer time for those.

Cleaned the throttle body and VVT Solenoid no joy. Loads of water sprays out the exhaust and it smells rich. It is hard to try and properly understand the problem without me being able to drive it. Thanks for the reply.
#4: Re: Throttle killing engine and running rough Author: Timon2210, Location: PalestinePosted: Fri Apr 24, 2015 1:24 am ---- Well from what you described,I believe the problem you got is with spark plugs,or a faulty coil pack. which make the car run on 3 or 2 cylinders instead of 4,which explains the rough idle,and engine being killed when you try to move.
#5: Re: Throttle killing engine and running rough Author: JoeMc96, Posted: Fri Apr 24, 2015 11:56 am ---- That could possibly be the cause because cylinder no 2 around the spark plug is dirty whilst the others are like new and the coil pack on no 2 is sort of dirtier than the rest plus they are ngk spark plugs not bosh which they were when I replaced them. Cheers
#6: Re: Throttle killing engine and running rough Author: JoeMc96, Posted: Fri Apr 24, 2015 11:59 am ---- But would that not come up on the diagnostic?
#7: Re: Throttle killing engine and running rough Author: Timon2210, Location: PalestinePosted: Sun Apr 26, 2015 2:32 pm ---- if it got scanned with the right tool,you will see the fault codes,and also you can have live data from the ignition coil.
#8: Re: Throttle killing engine and running rough Author: JoeMc96, Posted: Sun Apr 26, 2015 3:51 pm ---- Was scanned with Peugeot planet and came up with nothing. He was saying about the VVT Solinoid is all that he can suggest because it was not responding to revs as it should when looking at live data. Can't get in touch with Peugeot until tomorrow. Hopefully shouldn't be to much. Changed coil pack and replaced plugs with bosh and no difference.
Had scanned today with a fault reader and brought up P0107 and P0113 which I believe to be the MAP Sensor.
Cheers
#9: Re: Throttle killing engine and running rough Author: JoeMc96, Posted: Tue Apr 28, 2015 10:12 am ---- Just got scanned by another garage and brought back P0075, p0012, p0013, p0107, p0201, 202, 203, 204. Could the ECU be the cause of all this?
Cheers

I am thinking bthere could also be a headgasket problem though I haven't cross referenced your codes.
#11: Re: Throttle killing engine and running rough Author: JoeMc96, Posted: Mon May 04, 2015 11:51 pm ---- Not much. It is coming up map sensor low voltage and that misfire on all 4 cylinders. Circuit for the injectors on all 4 cylinders malfunction
#12: Re: Throttle killing engine and running rough Author: Steve206, Location: UKPosted: Tue May 05, 2015 4:13 pm ---- Faulty map could be over fueling or under fueling the engine. Start there
#13: Re: Throttle killing engine and running rough Author: JoeMc96, Posted: Tue May 05, 2015 4:32 pm ---- Changed map sensor coil pack can shaft sensor full service
Could it be the ecu with it saying MAP sensor circuit low input and all 4 injector circuit malfunction
Thanks
#15: Re: Throttle killing engine and running rough Author: JoeMc96, Posted: Tue May 05, 2015 5:36 pm ---- No but it has removed fault code
#16: Re: Throttle killing engine and running rough Author: JoeMc96, Posted: Wed May 06, 2015 5:22 am ---- I'm just worried it could be wiring or ECU related if so I have no chance of doing it Well at least I don't think so. With it bringing back circuit malfunction for all 4 injectors.
The problem is only below 2k revs sweet as a nut idling and over 2k
#17: Re: Throttle killing engine and running rough Author: Steve206, Location: UKPosted: Wed May 06, 2015 6:06 am ---- Can you check your lambda readings?
#18: Re: Throttle killing engine and running rough Author: JoeMc96, Posted: Wed May 06, 2015 6:31 am ---- I would have to pay someone with PP to come back out, would that cause circuit malfunctions though?
Cheers
#19: Re: Throttle killing engine and running rough Author: Steve206, Location: UKPosted: Wed May 06, 2015 7:43 am ---- I just think it's inusual that pp2000 found no faults but a generic scanner did. I would be thinking fuel or spark for lumpy idle.
