Few Problems Here Failed M.o.t

[205johnnyxsi 0]

Now then , bit help please got 10 days in which to get her back to the m.o.t testing station

 

1.6xsi 309 1987

 

001: Nearsie front position lamp(s) not in good working order (not working )

 

002: nearside lamp not in good working order adversely affecting beam image

 

003: exhaust emissions hydrocarbon content excessive

 

 

 

 

 

emissions test:

 

co %vol: min limit---- Max limit 3.500 .... actual Value 0.194 Pass

 

HC ppm vol: min limit---- max 1200 actual value... 2536 fail

 

idle speed pass

 

smoke level pass

 

 

 

whats is hc ppm vol ... fail.... he was on about my idleing or something, ive advanced my timeing when i had a indo kit on it could that be it.. ive played with me air/fuel mixture screw as well... please help i want her back in no monday...

 

she failed on coil being upside down thats dew to last owner lol

 

please could you tell me the fixers or what i can do

 

 

 

thanks johnny

so you need a new N/S headlamp and sidelight bulb.

 

I cant remember what causes the HC to go high though, has the car been sat for a while?

 

there is no up and down to a Pug coil, they'll fit either way.

its g maxs on them not standard.... the bloke said i needed to dry the lamp out.... i have a blowing exhaust as well thats getting welded sunday .... could that have oat to do with the hc ???? thanks Johnny

How do i go about lowering the hydrocarbon content down

 

as you can see it isnt best at 2536

 

Thanks johnny

my ford maverick failed exactly the same last year. changed the oil and hey presto. could be a multitude of things though . i was recommended to 1, change the oil, 2 give it a good thrashing on the way to the testing station (to within an inch of its life) and i beleive there is some magic 'mot pass in a can' type fuel additive which i cannot remember the name of.

redex that ? o dont worry i did but i dropped it off at 9:30 and it wont tested to 11 due to me being at work at 10 but on a different shift nexted week so it be a 3 a clock one and dont worry everytime im in her she gets put to her limits lol ... only just changed the oil well few months a go but its prob done 20 miles since change

 

and new filter...

 

do u no if 2536 is high ?

 

and what should it be ?

thanks J

how about replying in english ? text speak is not allowed and i suggest you re-read the forum rules.

 

please dont drive like a cock everywhere. the rest of us have family and friends that we care about and are using the same roads.

 

1, if my maths is correct then 2536 is definately higher than 1200

 

2, it should be lower than 1200

 

sounds like you've killed it . sell it and buy a corsa

 

cheers, Al

yeah sorry about that ...

 

ill get it done got it running idleing rebuilt back brakes and everything else brake pipes ect ... and im a novice

 

buy a corsa dont talk wet

My HC are approx. 4000 at idle.

The MOT testers are allowed to raise the idle to 2000rpm where upon it passes easily.

You can also block off the two breather pipes which go from the inlet, before the throttle body, to the oil filler cap. Block the small hole on the oil filler cap and a pipe from the other hole to a catch tank. It stops the crankcase gases from being recycled into the inlet.

[johnsimister 10]

The hydrocarbons are unburnt fuel and/or oil. Typically an injected XU 1.6 or 1.9 produces about 100 to 200 ppm (parts per million) at idle if it's in good tune, and it should also produce between 1 and 1.5 per cent CO (adjustable with the mixture screw on the airflow meter provided the meter isn't worn out). So your combination of very low CO and very high HC suggests a massive misfire with unburnt fuel going straight out the exhaust pipe. The engine must feel appalling to drive.

 

First off, change the plugs. If that doesn't help, see if there's a problem with the ignition leads, distributor cap and rotor arm. It might be a good idea to replace them all anyway. Another possibility is that the ignition timing is massively retarded, in which case the engine will feel flatter than a pancake. Whatever, something is seriously wrong.

[johnsimister 10]

Just to make it clear:

 

HC = hydrocarbons, ie unburnt fuel or oil.

CO = carbon monoxide, a product of incomplete combustion which occurs when there isn't enough oxygen present.

 

CO itself can be burnt (or 'oxidised') and then becomes CO2, while burning hydrocarbons when there's plenty of oxygen around makes water and CO2 which then may or may not make the planet warmer depending on whether there are enough plants to absorb the CO2 and make it react with water to make plant tissue. But I'm straying off topic here...

 

Nearly all engines emit some CO at idle, when combustion is at its least efficient. But if there's a catalytic converter, the CO gets oxidised to CO2. Which is good, because CO is highly toxic and CO2 is not toxic at all.

Sounds to me like it needs setting up properly by someone with the right equipment to test your emissions while they do.

ive advanced my timeing when i had a indo kit on it could that be it.. ive played with me air/fuel mixture screw as well

Has the car still got the induction kit fitted & if so has the AFM been adjusted to allow for it? Fitting an induction kit doesn't need anything changing to the timing but the fuelling does need some adjustments to the AFM by a professional. These two things can easily combine to cause you to fail an MOT on emissions.

 

A leaking exhaust can cause quite a difference to the HC emissions also iirc.

no fitted the standard kit back on before the m.o.t runs hell of a lot smoother and idles better, advance the timing dew to engine before that happend... but its booked in for timeing to be done.. beacuse the co is at 0.9 i have been told to bring it up to 3 beacuse its pre 89 im aloud it to go up to 3.5 with bring the co up to 3 ive been told it should bring me hc level down also with my exhaust being welded and timeing sorted, i think its more advanced... but then again im only a novice.... also with my springs one is upside down but g-max sent them out like that .... so looks like ill either have to get a compress to compress the spring back down to re-fit or book it in for it to be done.... just dont want to be robbed at the garage.. told him do what it takes to bring it down but you no what garages are like lol

 

 

essayyyyy

thanks johnny

it also flames like a buggah when been revved hard could be exhaust or un burnt flue you oppinions?
