failed mot help

[stevie 4]

i have a 93 import and failed my mot on emmissins and nothing else. the guy tried very hard but just could not get them to pass. the guy has said to me that he thinks it is probably the lamda sensor from the readings. the car has no mods except from a d/v, panel filter and a s/s excaust from cat back.

can anyone point me in the right direction to somewhere where i can get the correct lambda sensor for my car for as little money as possible

you will have to wire it in yourself as it is a universal one

OE ones are just too expensive

Your car is an import and the law states that imports made before Aug 95 dont need a cat, same as a UK car built before Aug 93.

Granted your car may be running a bit rich with the lambda issue, but when thats sorted you shouldnt fail if you are in that catagory.

complete noob question again but is it the four wire sensor i need

[cupradave]

think you will find its a 3 wire but get your head under the bonnet and check []

That's what will be music to my ears come MOT time []

I am not sure but would shoving a recirc dv back in make the car run less rich ? Might be worth trying as it is very easy to change over.

I might be talking nonsense though but it does affect the fueling assuming your DV is a VTA

thats fit i was thinking too. perhaps thats why lambda is on the way oot. 

 

edit:

 

would have been tested under no load though.[:$]

 

of course emission test would be carried out under strict idle as well [] []

Meant to add that the cat will be heavily polluted too if the car has been running rich. Cat will be less efficient basically

How warm was the engine when it was tested ?

the car was not to hot as i never got a chance to take for a run before hand and the mot station is only a 10 minute drive away. i'm going to put the original d/v back on as the one on is a dta,change the lambda and put some cataclean through it and keep my fingers crossed
