C02 emissions high nct

[decdd19]

Hi car went for test last week failed on high idle on emissions test can't be over 0.30 mine was 0.64

Lambda and low idle envisions are perfect

Spark plugs need changing as I forgot about them

Anyone know the readings o should get testing map and tps sensors with multimeter?

I have charcoal canister removed but don't think should make a difference

diptane and make sure to roast the cat just before test !!!! works a threat

[decdd19]

double the limit doubt diptane would bring it down enough? Fairly confident I had the cat good an hot but will look into it before retest

High CO2 points to running rich. Or blocked air filter in some cases.

Running rich I'd imagine as I currently am not using an air filter... how can you check tps an map sensors? Changed spark plugs an there was quite a bit of sut on them

[decdd19]

Done abit of a search on the Google I'd say I need to get my tps set up as I just threw on the throttle cable an tightened it up

Theres a good guide TGTT in the wiki section about how to set up a TPS

Replaced cracked manifold and gaskets at the block ,the turbo and turbo to cat got tested at local garage and have it down to .33 but lambda is now reading slightly high.. would a leak after the cat cause this

lambda high yes for leak

Lambda back down found leak now the Co is back up through the roof lol
