really at a loss now! please help :(

[Freeman_1986]

i have tried everything to sort the misfire/power loss................it basically misfires at low revs in every gear. feels like its struggling for fuel, untill i put my foot down then it picks up without misfiring, but has a distict loss of power. not all the time, comes and goes. can go a couple days without misfiring/struggling... but then will do it all day for a few days. theres no pattern, just when it feels like it....

also when idle, the exhaust chuggs/splutters a lot. this is constant

list of things i've changed (all new parts)

coil pack
leads
spark plugs
oil change and filter
knock sensor
crank sensor

i have also just checked all the injectors and they look clean enough and look like they are putting enough fuel through.

only other thing i can think of is the fuel filter.... as the problems started when i let the fuel run to red light everytime for a week or 2, and only topping up with £10 at a time, as had unusually high bills that month and was skint cos of it. could that have caused s**t to clog up the filter?

its just the randomness of it that throws me... dont want to have to take it to a garage really, lst resort,,, but cant think of anything else. i love the car to bits, and when it was running spot on it was an absolute pleasure to drive, but its becoming a real chore now and dont want to drive it...

any help??

 

[t444smh]

Map sensor maybe? Any warning lights on dash?

 

[SBV116]

Have you had a diagnostic check!?

 

[Jjay]

have you used some of that fuel injector cleaner?

 

[Freeman_1986]

no EML. used to come on intermitently, flash for a minute then go off. yeah got plugged in. just came up with knock sensor and random misfire. changed the sensor, got plugged again and wiped the errors. but still doing it.

havent used injecter cleaner... surely if it needed cleaning then it would be constant? not on the random..

 

[Jjay]

cos the injector cleaner would go through fuel pump and clean that too wouldnt it?

 

[scotty2hotty81]

Faulty injector?

 

[TheEvilGiraffe]

I don't understand the logic (and it's not just you chap!) behind crap in the fuel tank. What do you put in there apart from petrol ? And also, do you think the pick up for the pump/filter is going to be at the top of the tank .....?

I can't help you on the misfire.. could be 101 things. Sorry. MAP/MAF might be my guess but I've no idea what the Ph2 FBW throttles run.

Good luck !

 

[Jjay]

if TEG dont know your screwed xD!

 

[mr.pink87]

Oxygen sensor, as car seems to run fine on full chat (o2 signal ignored by ECU)?

 

[Rob669]

A long motorway journey always makes mine better, but hear what you say about cash. Mine does it sometimes, just hesitate and then picks up again ok. I have just bought another engine with all the sensors. I will try a new sensor every week and see if it changes anything. I'll let you know.

been told this loads of times by people, let the fuel run down and will drag the crap through ur engine lol u make sense tho. i have absolutly no clue about engines, and tbh was quite pleased with all the stuff i had managed to change myself before needing to take it to a garage, as easy as the work would be to some people. first time i've actaully had a go putting things right myself with an engine. though looks like its gonna have to go to the garage

 

[SBV116]

My guess would be injector, shot in the dark like!

 

[crombie1]

i fail

 

[crombie1]

lol its like you have coppied my thread. iv changed everything like you have and now i think its down to a faulty lambda. mine feels like its getting no fuel then all of a sudden its of, see here http://www.cliosport.net/forum/showthread.php?599964-new-182-owner-problems-already

 

[FAST_aD13]

Do you have a piggyback ecu fitted?

I had exactly the same symptoms when my piggyback ecu (dastek fastchip) went heywire

yeah i saw yours mate... i would have thought the lambda would have shown when plugged wouldnt it?

no mate i havent

 

[SBV116]

Sorry i thought it had constant miss! just read it again, pre cat lambda are pretty common aswell!

 

[Freeman_1986]

would that caused it to miss randomly? just it didnt show up when plugged in

 

[TimR26]

I'd take it to a garage it'll be cheaper than fixing it by trial and error.

 

[Stephen16vGSi]

TDC sensor?

 

[Chris62]

Lambda sensor would have been my first thought.

Mine was miss-firing coughing spluttering and was pretty much undriveable until i got it changed.

thats it tho, its not undrivable :/ drives fine, but then plays up. even when its at its worst you can still drive it fine, just lack of power and misfires at low revs...

 

[Freeman_1986]

TDC sensor?

said i changed it. got the new blue one with the updated loom etc.....

 

[olliewebbuk]

You tried everything but what you should have done to start with.

Take it to someone who has a decent code reader.

If you had done this you would probably have saved a load of money buying parts you didn't need to.

It got scanned by a proper reader at a garage...

 

[olliewebbuk]

A Renault CLIP then? If not do that.

 

[Rob669]

TDF in East England have a good reputation for sorting out such niggles

 

[Dan519]

for fault codes? or actual live data? fault codes will only really tell you when a sensor is dead as a doornail, or unplugged. If it's giving spurious readings the ECU will still think it's fine

 

[Freeman_1986]

Just booked the car into renault for tomorrow

 

[Gaz_]

i'd have gone for Lambda, or possibly map first tbh

 

[Dan519]

i'd have gone for Lambda, or possibly map first tbh

lambda is almost always my first port of call. They're unreliable and cause all kinds of strange issues

 

[shaggydog]

hi have you found the cause of the problem because it sounds identical to how mine runs?

 

[Rob]

Reading this my first thought was lambda. We'll see I guess.

 

[Tony Hunter]

Believe it or not mine has started doing this.
If I just jump in and drive off it then starts spluttering like it's firing on one cylinder.
If I leave ticking over for 5mins,then drive off,it's fine.

Too much sh1t under the bonnet of these road cars imo.

 

[Chris205]

My ph1 used to splutter when cold on light acceleration, think it was overfuelling

Are you doing karting next weekend? I'll bring my diagnostics kit and confirm it's Lambda

 

[Tony Hunter]

Yes,I'm there.
Thanks Dan.

I took a tank off not long ago and there were particles of debris in it but yeah it wouldn't / shouldn't make the engine as that is what the filters for :S
