the p100 failed its MOT on its emissions. limit is like 3.6 or something and its 5.5.
what could be causing this high emissions?

 

knackered lambda sensor posibly, or air temp/ coolant temp sensor maybe cooked, is the engine otherwise standard?

 

Or air mass sensor could be dodgey

 

nice observant tags?
glad someone found it funny

anyway yeah, it is otherwise standard. and the lambda sensors were just welded up on the engine i bought, but its passed for the last couple years until now.
il have a look into the sensors, its worth saying that the car has been sitting in the workshop for a few weeks.

 

Just give it a good thrashing before you take it back in, seemed to do the trick for my car.

Big-Dan.

 

What engine fella?could be an electric pot somewhere to adjust the co2?

 

24v cos.
looked on the back of the ECU and there isnt that white screw thing that the 4x4 YB cossys have

 

if it doesn't have any lambda sensors on it the fueling will never be right,
try giving it a good kicking, failing that just square the guy up if thats all thats wrong

 

Sounds about right to me,no amount of adjustment would bring that in,although ill check the autodata to see what's what.

 

Did you take the car for a good run before the MOT?
