has the idle gone up?

check for air leak on 1 way valve on servo pipe,thats what has just caused mine to overfuel

the blackness is from the over fuelling although ul get a certain amount of soot like on all cars...

i will get it moved then this week, as it costing me a fortune to run at the moment especially as i use V-power and not normal un leaded.
would this also be why im getting black shit coming out the exhaust?

i would think that the sensor is playing the part in the over fuelling yes.

have checked spark plugs and 1,3 and 4 are normal but 2 was black.
also have noticed black shit coming out the exhaust.
would fitting the lamba sensor in the correct place cure this?

it is because of the lamba sensor on the exhaust manifold.
just checked on ngk website and it will back fire and pop as the gases are only passing the sensor on 1 outlet not all 4 so 3 outlets are missing the sensor completly.

Feel free to take this with a pinch of salt, I'm a biker really.

But popping etc on a bike is usually air getting into the exhaust system, normally a broken clamp or similar.

if there black on the spark plugs this is a sign of over fuelling. possibly blanking it off may help but i only had experience with a standard manifold.

the plug that goes into the manifold?
ive got a protech exhaust manifold and the sensor is in 1 outlet not where it should be (into all4)
will blanking it off until i get i moved help?
and would checking the spark plugs indicate over fueling?

i thought if a sensor was playing up the eml would come on and there would be a fault code. have done a diagnostic test and no codes where found.
where is the lamba sensor?

i very much doubt its to do with a derestricted airbox. normally a sensor or plug/lead etc.

its had a new temp sensor as i had another engine fitted a month ago, so plugs and leads are new air filter is a courtenay panel filter which is clean.
could it have anything to do with it having a de-restrictive drilled airbox?

Try serviceing it , new lambda sensor, temp sensor, clean air filter

would there be a fault if it were over fueling tho?

backfiring and popping is usually over fuelling? im not sure the cat would be the first place to start?

how would you tell if the cat is fooked on a gsi without taking it off?
have noticed my gsi back-firing and popping recently and im not sure if the cat mite be fooked.
would take it off but im not a fan of re-fitting exhaust systems with just a jack holding the car up.
