Slight misfire, no eml...



  2014 Clio 200t edc
Does anyone know if the car should still run if the map sensor is unplugged? I unplugged mine and the engine stopped. Is that normal?
I've fitted genuine leads today so that just leaves the plugs to be changed when I can.

Took the spark plugs out today to show how they look. Apart from the ring of rust around the base of the ceramic, they seem ok but the car still runs lumpy. Can anyone 'read' spark plugs? @bloke or any other resident experts.

Cat just died yesterday. Wouldn't start at all and left me stranded in the dark.
Checked under the bonnet and by chance checked the coil pack plug. It wasn't sat correctly so once snapped down the car started and drove. Strange.
I'm starting to think this car definately needs to be plugged into clip to find out what's wrong. The spark plugs look ok as per pics above but I'll change those next I think, can't hurt. Also the swapping of the lambda front to back has done nothing but switch the error code from front to back. I would've thought that if it was actually at fault and causing the issue it would run better when moved to the back, unless of course both are goosed. I've also cleaned up the map sensor and tdc sensor too which is a blue plug version so has been changed at some point.
Has anyone in Stafford/Cannock got access to clip?
The car isn't cutting out at idle or slow moving but it does get close. I'm still thinking a slight blockage in injectors or a slight fault with them but I don't know.

only just seen the tag sorry, been off. plugs look ok, nothing jumps out put it that way. definitely need to look at live data.

No problem, thank you. I need to find someone with clip or something that can read live data close by really. I can't see it being the lambda because since switching front to back the error which keeps coming up is now showing the rear one as a fault. However that wouldn't cause running issues would it?

Just on the off chance I purchased and fitted a genuine blue Renault tdc. It runs a little better however touching the wires makes it cut out. Interestingly some monkey has been here before, the old tdc was a blue plugged spurious part and a replacement blue wiring loom has been fitted although it doesn't look a great job. Red wire connectors etc.
The problem appears to be that the wires are joined quite close to the black wrapped part of the loom where the wires dissapear into. Can the wires be pulled a little more out of there to replace with a genuine plug and wires? Could there be damage to the original wires here and would it cause poor running?

Looks like you have found the culprit then. You could test the wires for continuity and that would tell you if there was a break and with which wire, but it sounds like its the plug itself. I'm sure it wouldn't be an issue to strip some of the loom covering off to solder new wires on with the new plug and then fit the sesnor. It will need setting up/calibrating, if you speak to @oVerboost. he has just replaced his so might be able to give you an idea or what needs to be done.

Think I might have found the problem and now I've barely got it running at all. Yes those are bare wires just as they enter/exit the wiring loom. Coolant sensor wiring too. :( @MicKPM is that something you've seen and dealt with before? Just wish you were closer!!
Getting to hate this car now!!

Oh dear that doesn't look good, does the coolant sensor actually work? Probably worth just putting in some new wires.

It did do, but since disturbing it the gauge sways like a drunken sailor!! Lol
I would do if I had the ability, plus it disappears straight into the hard bit of the loom.

Its not hard to solder a couple of wires i remember you saying @NorthloopCup helped you before so maybe he could do it for you?
Fingers crossed someone can help and it won't cost a lot. I'm running out of money, patience and interest now unfortunately. Hope to get it sorted though asap as I'm stuck without a car.

Just take it to Mick if your not confident or another specialist if that's too far. I can't imagine it would cost you more then an hours labor and some solder lol.

Atleast get something around them so they're not touching each other then take it somewhere. Even an auto electrician.

thanks guys. ive pm'd @NorthloopCup and im also waiting for an auto electrician to call me back. if @MicKPM wasnt so far away and i could trust it to get there i would take it to him, but its not worth the risk of getting stuck miles from home. fingers crossed it will be sorted soon. :/

Well, borrowed a soldering iron today, bought some solder and electrical tape and had a go. Was out hunched over the engine bay for ages and it just wouldn't work so gave up. Sat in the house moping around and thought I'd give it another go, and it worked!! All fixed for now and the car is running. It appears to have fixed the hesitation but I've only tentatively tried it on a short run to check it. Really happy with my efforts to be honest!!
Also upon fixing/messing/braking things I found it had a genuine Renault crankshaft sensor loom fitted but a non-genuine sensor fitted. So fitting the gen sensor and also fixing the broken wire hopefully has sorted the issue. Thank you to everyone who has helped with this issue and given advice.

looking at what you've found i'd say the loom will have more issues with it. could be worth pulling it and stripping it back and going over it.

I might take it somewhere to have them check it over, after today I don't want to mess with wiring ever again! Lol

once it's off the car it's dead easy to work with. worst bit is getting the starter wiring off.

unplug everything off the engine, couple of trunking bits bolted on as well and it disconnects in the fusebox under the bonnet.

Don't get it
I listened to the advice, Although due to work and family commitments recently I wasn't able to take a day out to travel to a specialist I would trust (not the one on my doorstep that change cambelts with tippex) However I have found an issue, rectified it and it appears to have solved the issue. Now that it is working correctly I will be making time to get it checked over. I appreciate everyone's help with this.

Glad it's finally sorted out, just a tip you should use heat shrink instead of electrical tape to cover the bare wires.
