Fao Ben R or Anyone Techincal (not nick)

[Tom]

Sorry to bother you, with mundane issues.

My clio (1.216v) runs really bad when cold , and runs slightly rough when warm but its barely noticable then.

i changed the plugs which were mashed, but thats not fixed the problem.

Any ideas?

I need to sell it quick sharp.

All two-strokes run lumpy Tom...

 

[Tom]

Very funny. well funny infact

 

[iPap]

Sorry BenR was busy and asked me to take over his forum duties for a few hours... I think hell be pleased with my analysis and response!

 

[BenR]

indeed....nicks answers are acredited and he has been empowered with forum immunity of always beign correct hehehe.

Explaina tad more Tom. What do you mean by bad when cold and rough when warm. Is it lumpy, chokes, stalls, stutters, spits back, loss of power, funny noises?

 

[jon_r]

Well he poured a bottle of slick 50 through it and it made no difference

 

[BenR]

really? lol

Lumpy and it splutters a bit too. loss of power and the exhaust stinks of fuel (sometimes) but once the engine heats up its fine.

 

[BenR]

tried a new CTS?

or your lambda.

 

[Tom]

Ok. will have a go with those.

i thought it might be the lambda Cheers

 

[BenR]

you cna check your lambda supply voltages with a multimeter if you wish.

when hot it should be around the 0.5v mark

 

[jon_r]

Just to check, CTS is the cold timing sensor?

 

[BenR]

colant temp sensor

 

[BenR]

If it reads and supplies incorrect info to the ECU, the ECU in term will supply incorrect fueling.

 

[jon_r]

Thanks Ben

 

[Tom]

Cheers ben. thanks.

most running faults on the 1.2 d4f engine are cured by reprogramming.there are a lot of tech notes about running faults that your dealer will have access to and most of the repairs are petrol injection reprogramming.the output from a lambda sensor is-on the sensor before the cat the voltage will fluctuate between 200mv and 800mv.the sensor after the cat should have a constant output of about 600mv.
