hi guys, on a recent emissions test the reading on the g was 12%, so after reading a couple of posts on here i replaced the lambda sensor but when starting up you can still smell the petrol and the inside of the exhaust is blacked up. Any ideas what to investigate next that could be causing this.
cheers grant
check or change the blue temp sensor
how do u check it? do u have to remove it?
cheers

whats yr co pot set to?
My car also seems to run abit lean,
How'd i go about checking the "Co Pot" pete? Mine seems to have been tampared with in the past due to missing blue cap and screwdriver marks in the black "cap?"
Thanks
sorry guys, your quite correct rae it is in the FAQ section. Cheers guys am off to have a read and take notes.
cheers grant
have you got a de-cat pipe? emissions will be higher without a cat
yeah its de-cated but thats not enough to cause this much overfueling
get a multimeter over the two end pin of the plug
usually abotu 550 ohms
yeah am goin to test that tomorrow and the blue temp sender.
cheers grant
My Co2 Pot was 508 Ohms (think i done it correctly)...
So is this bad? Does this mean it is running richer then it should? How do i solve it?
Thanks
Ps: Sorry for a little thread hijack, posted here since both have same problem
Anyone?
you need to take it to a garage and put it on a gas analyser to set the co pot. 500ohms is a bit low though, I usually set it more like 600-650ohms as a base setting.

Would this mean its running rich or lean? having low ohms on my pot
lower means richer yes.
Okay gdgd,
and the only possible way to fix this is going through a garage correct?
Cheers
well you can try setting it to more like 600-650ohms but the only way to really set it is on a gas analyser yeah.
Sorry if this is a stupid question,
But how do i go about setting it closer to 600-650?
it's covered in the faq engine checkup thread. You need a multimeter and read the resistance across the outer two pins on the sensor
Yeah i've done that, but its reading 500Ohms...So how would i go about making it read 600ohms?
Cheers :)
turn the screw on the side of it
Cheers,
Sorted it now, got it at 559 Ohms :)
