OK just tested with me mate the MAF sensor as we couldnt find any other problems regarding high CO

Now we pulled the intake hose half off the MAF sensor and we rapidly saw the CO% dropping like a rock! tested it a few times and same occurs.

MAF sensor fooked i reckon???

Can i clean it or just stick a new one in?

Every Small turbo with running problem I have seen has aways been the AFM, Does it have a cone filter on it.

Mark

 

yes mark it has but as i disconnected it it stalled and the engine went out so figured it might be working ... looked inside and didnt really lkooked dirty .. but i reckon its fooked then ?

 

Check the cone filters breather return most I have seen go straight in to the AFM measuerment hole not good for reliabilty.

it sits like this mark:

 

That looks fine.

But given then info from the first post mark CO dropping when i have the hose a bit off the MAF and the CO is spot on is that telling that the MAF is fooked then yes?

is there a way to clean it or should i stick a new one in?

 

carb cleaner the feck out of the hotwire element (take the sensor bit off it 1st)

see if it makes it any better

 

JIm was thinking of that but i also heared that carb cleaner doesnt dry without any residue

 

 

im not sure goon,,,,, i would have a go with the carb cleaner

 

will do before buying another see if it helps or not cheers mark, jim and last but not least Gareth might have found it then anyway

 

No, you shouldn't use carb cleaner. Use an electrical contact cleaner.

 

cheers for that bill fingers crossed getting it tomoz!

 

any spray on shit will do

 

I've used brake cleaner b4 and that works

 

Cheers Steve for the tip

But since i need to get either anyway will get some contact cleaner on monday

 

brake cleaner works VERY well

 

You could probably clean it using cotton buds or a lint free cloth soaked in alcohol, gently wiped up the wire - you could fit an oiled air filter to a vehicle with an AFM, but I wouldn't do any of those either

Maybe I should have phrased it I wouldn't use any other than an electrical contact cleaner to clean a relatively fragile AFM.....

 

and [b]'d[/]b just spray it with whatever aerosol propelled liquid i could find in the shed

lynx africa would work weell

 

 

bill like i said ive read that brake/carb cleaner dries up with leaving residue so will go for the contact cleaner just to make sure its the best option i can use
